Lots of people buy diamond rings from Blue Nile. After wearing them for some time, most people find their fingers get thicker. They have to resize their rings later. The resizing process here is totally different from local jewelry shops. Local physical stores do not need any online steps to fix ring sizes. Below I sort out full guides and different choices for you to refer to.

Main Official Way: Use Blue Nile’s own after-sale resize service

Blue Nile has official ring resizing service for buyers. But you must send your ring back to the United States for fixing. This is their standard rule for all customers.

How long will resizing take?

We tell all buyers to prepare a time window of two to three weeks for the full resize work. Do not plan any short-time wearing plans during this period.

What resize rules do they have for buyers?

Every buyer can get one free ring resize within one year after purchase. There are two ring styles they can not adjust size for. Eternity bands and tension rings can not be cut or stretched. Workers have to make a brand new ring from zero if you want to change its size.

Blue Nile provide free shipping label for you to send rings back to their US factory. Once resize finish, they send your ring back with free 2-day FedEx delivery.

One important point many people miss: international buyers need pay 50 US dollars for return shipping fee. This money can not be waived for oversea customers.

Step-by-step operation guide

Talk to customer service staff firstOpen Blue Nile official website, click “Contact Us” button on page. You can also use online live chat box to connect service workers.Tell them clearly that you need ring resize service, and hand over your full order number they gave you when you bought the ring. Without order number, they can not pull out your ring record fast.
Get price quote and shipping arrangementService team will check your ring information one by one. They look at ring metal material, side small stones, ring shape and other details. Then they send you a clear quote of resize cost.Workers will teach you every step to pack and ship the ring safely to their fixed US warehouse address. In most cases, they send a pre-paid shipping sticker to your email directly. You just print it and stick on your parcel box.
Ship out your ring and wait for resize workUse thick bubble wrap and hard small box to cover your diamond ring well. Drop off the parcel at appointed courier store.Blue Nile’s professional jewelry craftsmen will do cutting, stretching, polishing and stone re-setting work to adjust your ring size.
Receive your fixed ring back homeOnce all resize work pass quality check, Blue Nile pack your ring with gift box and send it back to your address.

Critical warning for buyers from Taiwan

You will face customs charge two times in full process. First customs check when you send ring from Taiwan to US, second customs clearance when US send fixed ring back to you.

Before you mail the ring out, you must chat with Blue Nile service to confirm correct goods value declaration words. Wrong declaration content will lead to double tax fees, which waste your extra money.

Pros and cons of official factory resize

Good sides: All resize work done by original factory craftsmen. The finish quality and stone safety get the best protection. No risk of bad re-polish or loose small stones.

Bad sides: It takes really long time. The whole back-and-forth shipping plus fixing work may take several weeks or even one whole month. International delivery also have hidden risks, such as parcel lost, broken package, unexpected customs tax.

Better local choice: Find trusted jewelry repair studios in Taiwan, Hong Kong and Macau

For customers live in Taiwan, Hong Kong or Macau, local resize service is normally much faster, easier to operate, and total spending can be lower than sending ring to US. This choice fit most oversea Blue Nile buyers better.

How to pick a reliable local jewelry shop

You can search offline physical jewelry stores or professional jewelry repair workshops around your living area. Many jewelry counters inside big department stores also take paid ring resize orders.

Search keywords like jewelry repair, ring resize on internet browsing tools. Read real buyer reviews under each shop page to judge their service reputation. Avoid shops with lots of bad feedback about stone falling after resize.

On-site ring check with master craftsmen

Bring your Blue Nile diamond ring to the shop and let master look at it face to face. The master will tell you three key points clearly:

First, can this ring be resized successfully? Not every ring design support easy size change. For examples:

Rings fully set with small side diamonds: Craftsmen have to take all tiny stones out before cutting ring band. This action bring high risk of stone crack or lost during operation.
Tension setting rings and special craft bands: These structure can not stretch or cut, local masters can not adjust size for them too.Second, ring metal type. Platinum and K gold rings have mature resize craft, masters handle these two materials smoothly with little damage risk.Third, time cost and service charge. Most local shops finish resize work within several days. All fees are told to you in advance, no hidden extra money later.

Strong advantages of local resize plan

Save huge time: No cross-border shipping between two countries. You get your ring back in short waiting days.
Less troublesome steps: No customs paper work, no international shipping insurance problem, no unexpected tax fines. All complex overseas delivery troubles gone.
Smooth communication: You talk with ring master in person directly. You can show your exact demand, ask about craft details any time on spot.

Final important summary and practical suggestions

Contact Blue Nile customer service at first no matter which resize way you choose. Tell service your ring resize need in advance. Sometimes the brand can offer partial cost subsidy for your repair, or give most professional advice match your ring style. Do not skip this step easily.
Local resize should be your top choice. For most buyers from Hong Kong, Macau and Taiwan, sending ring to nearby trusted jewelry studio is the most sensible and highest efficiency solution.
Check your ring design before any action. Look if your ring has dense paved small diamonds all over band. Dense stone layout will raise resize difficulty and push up service price a lot. This detail decide if local master can take your order.
Keep all related paper records well. If you pick official US service, save shipping slips, chat screenshot with service team. If you use local shop repair, keep repair order receipt and all message records with master. These papers help you solve dispute once bad situation happen.

Last ultimate advice

If you care about convenient operation and fast progress most, just find a well-comment local jewelry repair shop in Taiwan, Hong Kong or Macau. Bring your ring for on-site check and resize service directly. This is the top solution to solve Blue Nile ring size trouble for regional buyers.

Diamond Inclusions: Cavity

Post author By Review
Post date July 14, 2024

Does your diamond’s GIA certificate mark a cavity? Do you know what this kind of inclusion is? The word cavity means hole in English. Most cavities form when other surface flaws like knots or crystals fall off after the diamond gets hit. A small number of cavities also come from broken feathers, which create sharp openings on the stone. It looks just like a tooth with cavities. The bigger the cavity is, the worse the diamond looks visually. For this reason, we do not suggest buying any diamond that has a cavity inclusion.

Gem experts have studied this issue for years, and they find cavities can appear anywhere on a diamond. Some buyers think diamonds with cavities on the girdle or edges are okay to buy. They believe the prongs of the ring setting will cover the cavity after mounting, so no one will notice the flaw. This idea sound reasonable, but it has hidden risks. As you wear the diamond longer, accidental knocks can make the edge cavity bigger and bigger. It will finally lower the overall quality of the stone.

Diamonds with cavities on the table are even less recommended. A large hole on the top surface will directly hurt the diamond’s fire and brilliance. Diamonds have a nature to attract oil and repel water. When you wear it daily, cosmetics and oily substances will stick to the stone easily. These oils catch dust very fast. Over time, dirt builds up inside the cavity, and it will look like a dark spot. This dark mark seriously ruins the diamond’s sparkle.

Recently, one follower send me two diamonds and ask me to help choose between them. I checked their GIA certificates carefully and found both stones have cavity inclusions. So I told this person to look for other options instead. There are countless diamonds on the market. If you compare more choices, you will definitely find a much better one without such obvious flaws.

Diamond rings stand for love. They are a vital part of wedding ceremonies. Picking a right diamond matters a lot, yet the band design also carries huge weight. A ring band does not only hold the diamond in place, it also shows the wearer’s unique personality and charm. Many buyers wonder, what are the common diamond ring styles sold at Blue Nile?

Simple designs create timeless classics. Six-prong and four-prong diamond ring styles have existed for hundreds of years. The iconic six-prong design has a history of nearly one hundred years. It is everlasting, minimal and can stand the test of time. The most famous examples include Tiffany’s classic six-prong ring, Cartier’s iconic four-prong bullhead style, and the HW ring from Harry Winston. Blue Nile also provides a wide range of six-prong and four-prong band options, and they look really nice when worn. Two typical choices are Petite Hidden Halo Solitaire and Classic Six-Prong Solitaire.

Bands With Side Pave Diamonds

If you think a plain band looks empty and lack decorations, you can add small side diamonds. The whole ring will then shine brightly, just like many little stars surrounding a bright full moon. Blue Nile has lots of choices in this category, such as Scalloped Pavé Diamond Engagement Ring and French Pavé Diamond Engagement Ring in Platinum (1/4 ct. tw). Some customers say this style catch eyes much easier than plain single stone rings. Small diamonds along the band add soft sparkles when hands move.

Halo Cluster Setting Styles

Do you want your main diamond to looks bigger and more outstanding? Or you hope your ring delivers a luxurious vibe? Then cluster halo styles will be your great pick.

Bands With Colored Gemstones

Lots of customers choose bands set with other gemstones mainly to show their personal taste. Rubies and sapphires paired with white diamonds create a extra luxurious and beautiful effect. The contrast between colorful stones and clear diamonds makes the ring one-of-a-kind. One representative item at Blue Nile is Round Blue Sapphire Three Stone Engagement Ring In Platinum By James Allen. These colored stone styles fit people who dislike plain all-diamond designs. Weddings with vintage or romantic themes match these rings perfectly.

What is the price of a one carat diamond?

When people hear the word diamond, they will easily think of wealthy ladies and socialites wearing big diamonds with many carats. Many people also wonder, how much does a one-carat diamond cost exactly?

First of all, let’s talk about carat. Carat is the standard weight unit for all kinds of gemstones and jewelry. One carat equals 0.2 grams, which is one fifth of a gram. To make it easier for people to tell the size of small diamonds, people divide one full carat into 100 points. That means a 50-point diamond is just 0.5 carats, and a 100-point diamond is exactly one carat. This counting way is widely used in the diamond market every day.

Now back to the main question: how much is a 1-carat diamond?

The price of a diamond is mainly decided by the famous 4C grading system. For diamonds with the same carat weight, their prices can be totally different because of different color, clarity, cut, symmetry and polish grades. Besides these basic factors, some extra features also change the price a lot. For example, diamonds with or without fluorescence will have big price gaps. Some diamonds have natural flaws like milky tint, coffee tint or green tint, and these problems will also make the price go down. So there is no single fixed answer to the price of one carat diamond.

A low-quality 1-carat diamond may cost around 3000 US dollar. If the diamond has good overall quality, its price can reach tens of thousands of US dollars. When it comes to high-quality colored diamonds, the price is even more amazing. A nice colored diamond can cost hundreds of thousands or even millions of US dollars.

Brand is another factor that affects diamond prices. Luxury brands sell their diamonds at a much higher price than regular diamond sellers. Most of the extra money here is just the brand premium, not the real value of the diamond itself. If you want to buy a cost-effective diamond ring, custom diamond rings are a great choice. There are many reliable online stores in this field. Bluenile, Jameallen, Whiteflash and Rarecarat all have good reputations among buyers. Jameallen has now merged into Bluenile and become part of Bluenile’s product line.

To sum up, the higher the color and clarity grades are, the more expensive the diamond will be. Never judge a diamond’s value only by its carat size. A diamond’s final price is affected by many different parameters together. When you plan to buy a diamond, you need to take all these factors into consideration carefully.

Guide to GIA Diamond Certificates

No Comments on Guide to GIA Diamond Certificates

GIA is short for the Gemological Institute of America. It is a non-profit jewelry appraisal organization based in the United States. Founded in 1931, it has developed for more than 80 years. Now it has set up many branches around the world, and it has become the benchmark for diamond grading. Many people come into contact with GIA diamond certificates for the first time, and they do not know what the items on the certificate stand for. Today we will make a clear explaination about the GIA diamond certificate.

Understanding GIA Diamond Certificates

GIA has two main types of diamond certificates: full certificate and small certificate. The full certificate is used for colored diamonds and large carat diamonds. The small certificate is applied to diamonds weighing less than one carat. The biggest difference between them is that the full certificate prints a diagram showing the distribution of inclusions inside the diamond, and its size is also larger. Every diamond has unique inclusions in different shapes and positions, so this diagram can well prove that each diamond is one of a kind. We take round diamonds as an example to explain the details of the certificate. One important point you need to know: GIA will not give cut grades for fancy shaped diamonds.

GIA Diamond Certificate

The left side of the certificate lists key information from top to bottom.

Issue Date: September 01, 2017

GIA Report Number: 6265698118

Shape and Cutting Style: Round Brilliant

Measurements: 5.41 – 5.43 x 3.33 mm

Carat Weight: 0.60 carat

Color Grade: H

Clarity Grade: VS1

Cut Grade: Excellent

Polish: Excellent

Symmetry: Excellent

Fluorescence: None

Clarity Characteristics: Needle, Pinpoint

On the right part of the certificate, you can also see the same GIA report number. This number matches the laser engraving on the diamond’s girdle. There is also a proportion diagram of diamond cutting parameters, grading notes and anti-counterfeit codes. A QR code is attached here too. You can scan the code or visit the official GIA website to check all detailed information of this diamond.

Astor By Blue Nile Replaced by Curated Diamonds with More Diamond Options

No Comments on Astor By Blue Nile Replaced by Curated Diamonds with More Diamond Options

Update: In 2026, Blue Nile stop selling Astor Diamonds. They replace it with Curated Diamonds now. Curated Diamonds bring big good for shoppers, it let customer pick their favorite stones without any stress. There are tons of filter options to use, hunting for nice diamonds won’t feel troublesome anymore. All the following text will focus fully on Curated Diamonds, not the old Astor Diamond line.

Every young girls dream to wear a shiny, eye-catching diamond ring one day. But many people meet a weird problem in real shopping. Some diamonds look dull and dim under any light, while others sparkle brightly no matter indoor or outdoor. Lots of buyers confused and ask why this big gap happen. The answer is simple: every natural diamond in the world is one of a kind, no two stones are exactly same. Even if we put aside the famous 4C standard for a second, different cutting and polishing work create huge differences on key proportion data. Those data include table width ratio, total depth ratio, pavilion angle, crown angle and more. All these separate numbers mix together and decide how much light a diamond can reflect back to human eyes. That’s why some gems glow strong and others look flat. A lot of new buyers don’t know the trick, they keep asking how to find a super sparkling diamond within their budget. Blue Nile launch Curated Diamonds, their top-tier ideal diamond collection, back in 2026. The brand pick out stones strictly through layers of checks, to make sure every single Curated Diamond own outstanding light performance. The stock range is very wide, customers can sort and filter stones by any diamond parameter or their spending limit easily.

All Curated Diamonds come with official certification from GIA, full name Gemological Institute of America. Every qualified stone must go through professional testing machine called BrillianceScope. This device test three core optical features of each diamond: Brilliance, Sparkle and Fire. Professional examiners score each part carefully, only stones get top marks in all three items can be labeled as Curated Diamonds. This strict rule make Curated Diamonds far better than regular loose diamonds on light return, colorful fire flashes and bright white shine.

Blue Nile put optical performance as the most important standard for Curated Diamonds, higher than carat weight or raw stone saving rate. When craftsmen cut rough diamond into Curated Diamond finished product, only 26% of the original rough stone can be kept. This low retention rate is the price for perfect cut. Every Curated Diamond reach Excellent grade on three critical cutting standards: cut grade, polish grade and symmetry grade. Workers do precise, handmade cutting process for hours to hit the perfect balance point. People may not know that Brilliance and Fire are two opposite index, when one goes up, the other will drop down. Cutters need to calculate and adjust every tiny angle to find the sweet spot where both brightness and colorful light work well together. Because the standard is so tough, only one out of one thousand natural diamonds can pass all tests and become Curated Diamonds. It’s a really rare selection.

In the early days, Curated Diamonds only have round brilliant cut stones. Now Blue Nile expand the collection with many fancy shapes. Shoppers can find oval, pear, heart, princess, Asscher cut Curated Diamonds and more styles on their website. Every stone in this line pass multi-layer visual screening. When you watch them with naked eyes, there is no milky haze or brown tint inside the crystal. No milk coffee diamonds exist in Curated Diamonds inventory at all.

Whether you want a ring for engagement, wedding or daily wear, these high-sparkle stones can satisfy all your needs, and you will not feel stressed when picking out your ideal diamond anymore.

Pear Diamond

As one of the most popular fancy shaped diamonds, pear shaped diamond is getting more and more popular among jewellery lovers all over the world these years. Lots of people choose it as their engagement stone for two simple reasons. First of all, pear diamonds always look bigger in visual size comparing with round brilliant diamonds with the same carat weight. Second, once you wear a pear diamond ring on your finger, it can stretch your finger line and make your hands look slimmer and more elegant. For a standard one-carat pear diamond, its length can reach around nine millimeters, and its width is about five millimeters, this data is a basic reference for new buyers who do not know much about diamond dimension.

If you take out a pear diamond and watch it carefully under soft light, you will see its special outline clearly. One end of the stone forms a smooth half circle, and the other end tapers down to a thin, sharp point. The whole shape looks just like a drop of water falling from the sky, or a single teardrop roll down from someone’s cheek. That is why many people also call it teardrop diamond in daily talk. Anyone who keep an eye on high fashion fine jewelry must have stepped into the boutique of Chaumet before. The brand’s diamond rings fully show the outstanding sparkle and brilliance of pear shaped stones, and they do it better than most luxury jewellery brands. The rings from their Joséphine Aigrette collection have already become timeless classics that represent a whole fashion era. Countless celebrities and royal families pick this series for their important life moments, and this push pear diamonds to become even more trendy in recent market.

There are many world-famous pear shaped diamonds recorded in jewellery history books, and two of them are the most well-known to the public. The first one is the Cullinan Diamond, which weights more than five hundred carats at its rough state. After professional cutting work, this pear diamond owns seventy-four facets in total. People mount this precious stone on the royal scepter of British monarch, and it still stay there as a priceless national treasure up to today. Another legendary pear diamond is the Taylor-Burton Diamond, with an original weight of 69.42 carats. Its first famous owner was Elizabeth Taylor, a super movie star with huge fame in last century. Later, a man named Robert bought this diamond from the previous holder. He sent the stone back to diamond craftsmen for re-cutting, trimming and polishing to fix its uneven surface and boost its light performance. After the rework process finished, the weight of this pear diamond drop to roughly 68 carats, but its fire and clarity got a huge upgrade.

The Ideal Proportion Range for Perfect Pear Shaped Diamonds

Different from round diamonds, fancy shape diamonds like pear do not receive an official cut grade on standard GIA diamond certificates. Gem lab workers can only sum up years of testing experience and sum out a ideal parameter range for pear stones, to help customers pick well-cut pieces with good light return.

The length-to-width ratio is the most important index for pear diamonds. The perfect range stands between 1.5 and 1.7. Stones inside this interval can release the best fire and brightness when light pass through the facets. If the ratio go above 1.7, the pear diamond will turn too slim and long, the half-circle end will look small and unbalanced. If the ratio fall below 1.5, the stone become too short and compact, lose the elegant teardrop feature that pear diamond famous for.

Other key proportions have fixed suitable ranges too. The table width ratio should stay 56% to 60% of the whole stone width. The total depth ratio need to keep between 59% and 62%. For the girdle thickness, medium thickness is the most friendly choice for daily wear; stones with thin or slightly thick girdle are also acceptable, with or without extra girdle facets both work fine.

I will always suggest every buyer check the real diamond in person before pay the bill. You need to avoid pear diamonds with heavy bow-tie effect. The dark bow tie shadow in the center will block light reflection and make the stone look dim and lifeless. Numbers on the certificate can only tell you basic data, you can not picture the actual shining look of a diamond just by reading those parameters. The online diamond retailer Blue Nile shoot high-definition video for every single diamond they sell on their website. When you feel confused and cannot make a final decision between several stones, you can enter their online zoom room to watch each diamond’s live video, rotate the stone and check its light performance from all angles. This online service greatly lower the risk of buying a unsatisfactory pear diamond without seeing real items offline.

Important Update!

JamesAllen and BlueNile have merged into one single brand. The Canada Mark diamonds, which used to be the core signature product of JamesAllen, are gone forever now. Let us take a moment to look back on this once dominant king in the diamond industry.

Canada is one of the world’s major diamond producing country. It is well-known across the whole trade for its top-tier high-quality diamonds. Most of its key diamond mines locate in the freezing tundra areas of northern and northwest Canada. These diamonds own premium quality with affordable prices, so they sell really well across North America and all over the globe. Gahcho Kue Diamond Mine counts as one of the largest diamond deposits on Earth, and it also is Canada’s sixth official diamond mine. Experts predict this mine could bring billions of Canadian dollars in economic revenue for the country. As global demand for natural diamonds keep rising year by year, more Canadian diamond mines keep expanding their operation sizes and launch new mining projects nonstop.

Canada Mark diamonds are noble and luxurious, the true king of gemstones straight from the icy Arctic tundra. Every single one of these stones reflects the stunning beauty of pure natural creation. Back then, JamesAllen, the famous custom diamond jewelry website, let customers own these brilliant gems that glimmer just like northern auroras from the freezing arctic lands. The whole journey of each diamond, from being dug out of mines to fully polished finished stone, was fully transparent and open for every shopper to check.

JamesAllen also rely on its powerful 360-degree high-definition display tech to show every Canada Mark diamond clearly to every website visitor. The zoom function can magnify the stone up to 40 times bigger. Many people don’t know that standard laboratory diamond grading equipment only support 10 times magnification. Simply put, only diamonds with outstanding quality got the confidence to be shown in such clear, huge magnification.

People who often browse the JamesAllen jewelry site could easily spot a CanadaMark tag in the origin column of loose diamond listings. This tag meant those stones mined inside Canada, all certified conflict-free diamonds. Every single Canada Mark diamond came with an official origin certificate to prove its source. If you are a lover of arctic-sourced natural diamonds, you could spend time picking your ideal stone there before the line stopped selling.

Now BlueNile holds a far larger inventory of loose diamonds in its stock library. If you run into any troubles or confusion when picking out diamonds, feel free to leave a message down below to ask us for help.

Oval diamond

There are many different kinds of fancy shape diamonds. Among all these styles, oval cut diamonds are one of the most popular picks for most people. From ancient times all the way to the modern day, lots of celebrities, nobles and high-ranking officials love to wear oval diamonds on their fingers or as pendants. Just like other fancy cut diamonds on the market, an oval diamond with identical clarity, color and carat grade will always carry a lower price tag compared to a standard round brilliant diamond.

One big reason for this price gap is the stone retention rate during the cutting process. When craftsmen cut an oval shape from rough diamond ore, more than fifty percent of the original rough stone can be kept and made into the finished gem. This retention number is much higher than round diamonds of the same carat weight. For this reason, oval cuts are perfect choice for long, rectangular rough diamond crystals that cannot be shaped into perfect round stones without wasting too much valuable material.

The oval cut diamond did not appear out of nowhere. It build upon the classic cutting framework of traditional round brilliant diamonds. Gem cutters kept adjusting, upgrading and optimizing its facet layout year after year, and finally turned it into the modified brilliant cut oval diamond we know and love today. A standard oval diamond features a total of 69 polished facets on its surface. The most ideal golden length-to-width ratio stands at 1.5. To put it simply, the best visual effect comes when the stone’s length is one and a half times its width.

If the length-width ratio go over 1.5, a dark shadow zone will show up right in the center of the diamond when you look at it from the top. This dark patch greatly weaken the diamond’s fire and sparkle, making the gem look dull and lifeless. On the other hand, if the ratio drop below 1.5, the oval will look nothing more than an elongated round diamond, losing its unique elegant outline. But if the cutter hits the perfect proportion range, the fire and light performance of an oval diamond can nearly match that of a top-tier round brilliant. It can catch every ray of light and easily draw every viewer’s attention at first glance.

Oval diamond ring

Standards for Perfect Cut Oval Diamonds

The table percentage of a well-cut oval diamond should fall between 53.0% and 61.5%. The total depth percentage needs to stay within the range of 59.0% to 63.0%. As for the length to width proportion, the acceptable standard interval is from 1.33 to 1.66. When it comes to the girdle, the ideal thickness range is thin to slightly thick. A girdle that is too thin will bring higher risk of chipping during daily wear, while an overly thick girdle wastes carat weight without boosting beauty. Only the thin to slightly thick girdle balance durability and visual attractiveness best.

Symbolic Meaning of Oval Cut Diamonds

An oval diamond owns a soft, gentle outline while still holding a strong sense of unique individuality at the same time. It is the ideal gemstone for people who have clear personal thoughts and dare to turn their plans into real actions. Many people from European and American countries notice that the oval shape looks just like an egg. For this cultural reason, oval diamonds carry the symbolic meaning of endless cycle of life and endless vitality. It stands for constant growth, new possibilities and lasting energy that never fades away.

From the perspective of astrology, oval diamonds suit people born under Aries and Capricorn star signs very well. The traits of these two signs match the energy of oval cuts perfectly. Capricorn people are famous for their persistent, tough and unyielding personalities, never giving up when facing difficulties. Aries people are straightforward, warm and kind, always speaking their true mind without hidden tricks. Both personalities fit the temperament that oval diamonds represent.

Besides its rich symbolic value, the special curved oval shape also brings great advantages when worn on hands. Its stretched outline visually stretch the fingers, making the whole hand look slimmer and more slender. For people with shorter fingers or thicker knuckles, oval diamond rings are a wonderful option to create a more graceful hand silhouette in daily life. Even for those with long fingers, oval diamonds can add extra elegant charm that round cuts cannot provide. No matter set in solitaire designs or paired with side accent stones, oval diamonds always deliver a delicate, eye-catching look on any wearer’s hand.
