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

All Blue Nile diamonds are worth buying? 1，Both milky tint and brown hue:Tap to see full diamond info 2，The diamond has milkiness:Click to view detailed diamond information 3，The diamond has medium green fluorescence.:View diamond details 4，The diamond has a cavity:See the diamond details
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.

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.

The color grading rule for diamond in international jewelry industry is really strict. Every country got their own matching evaluate standard. So you can only judge diamond color grade base on loose diamond, and do the test under strict lab environment. If you test a diamond ring with metal setting, the metal will mess up your judge result. Platinum setting can make diamond look more white, but rose gold will make diamond color grade look lower. That’s why you can not get a fair and right color score when the diamond still on the ring mount. Color grade is only one part that decide diamond quality. Don’t just think a I color diamond always looks better than J color one. You need look at the other three C too: diamond cut, clarity grade and carat weight.

Diamond Color Grading

Diamond rings shine so bright on fingers, the secret is loose diamond work like a prism. It catch natural light and break it into many colorful sparkles. The diamond’s own color acts like a light filter inside. If a diamond is clear and no color, it can reflect more bright rainbow flashes. That make colorless diamond more expensive than light yellow ones. Diamond color grade is a rule to mark how yellow a stone is. Higher grade means less yellow tint inside the crystal. Color is one of the four most important C factors. When people pick loose diamonds, they can’t ignore color. Human eyes first notice how shiny a diamond is, and shine level is heavily effected by color.
Grade D: Total no color. It is the top color level, super rare to find.

Grade E: No visible color. Only professional gem tester can find tiny bit of tint inside. This kind of diamond is really uncommon.

Grade F: Colorless grade. Only jewelry experts can spot little color trace, but it still count as colorless range. They are top quality diamonds.

Grade G to H: Near colorless. You can see soft yellow tint only when you put them next to D-F high grade stones. Diamonds of G and H grade still keep great market value.

Grade I to J: Almost no color. Light yellow shade can be detected easily. They have pretty good value for daily wear.

Grade K to M: Strong yellow color, low fire sparkle. Our wedding diamond ring store do not sell these grades, we tell customers do not choose them.

Grade N to Z: Dark yellow tint, bad light performance. Our shop never provide these diamonds, we also advice buyers stay away from them.

Grading color of diamond

Once a diamond finish cutting, outside things can not change its value anymore. Diamond color will not turn yellow as years go by. It is extremely hard to find a full colorless diamond, so D grade stones are rare and costly. Most loose diamonds have natural mixed tint when they form underground, like green, coffee and brown shades. These unwanted color will drop diamond’s worth a lot. Many shoppers ask, which color grade should I pick when buying a diamond? Everyone know the rule: colorless is best, darker yellow means worse quality. D to F are full colorless group. G to J are near colorless. K to M have clear yellow tone. N to Z carry obvious pale yellow, they almost have no collection value. But fun fact, N-Z yellow diamonds match gold metal very nicely. After Z grade, stones with full rich yellow color belong to fancy colored diamond category.
For daily shopping, better choose H or above I color diamonds. I and J grade still fall into near colorless group, but naked eyes can catch faint yellow shade directly. Fancy color diamonds use different grading rule. Their price depend on how bright and vivid their color is. There are many fancy diamond types: yellow, green, blue, brown, pink, orange, red, black, purple and more. All of them are precious fancy gems. Red fancy diamond is the most valuable one among all colored diamonds.

As one of the most important milestones in love, a engagement ring stands for that you and your partner are ready to talk about marriage and plan your future life together. Lots of people dream to gift their lovers a stunning diamond engagement ring, but many of them face a tight budget and can not afford fancy rings from offline physical jewelry stores. If this is your situation, customizing a diamond ring online will be a perfect choice for you. There are several well-known online diamond custom brands you can trust, including Blue Nile, James Allen, WhiteFlash and Brian Gavin. It’s worth mentioning that James Allen has merged with Blue Nile and they now belong to the same company, so their diamond supply and after-sales services share many similar resources for customers.

How to Customize Your Own Engagement Ring

The whole custom process does not sound complicated, but you need to follow clear steps to get a ring that fits all your expectations. The first thing you need to do is picture the exact style of diamond ring you want in your mind. Every couple hopes their engagement ring is unique and can not be copied by others, so designing an exclusive style carries great meaning. Next, finding a reputable and experienced jeweler to carry out your custom plan is extremely vital. When you send all your design details to the jeweler you pick, you should describe every single detail as clear as possible. Vague descriptions will make the finished ring far away from your imagination and waste both your time and money.

custom Diamond Ring

If you lack design inspiration and have no idea what style to pick at the beginning, you can browse thousands of finished ring samples on those online jewelry websites. The platforms offer a flexible matching mode: you can pick a loose diamond first, then match it with any ring band you like freely to build your exclusive ring. After you finish your combination, the website will generate realistic renderings to show how the final ring looks, so you can adjust the style before placing your formal order.

Set Your Budget and Learn About Diamond 4C Standards

Before you lock down any loose diamond, you have to set a clear budget and pick cost-effective stones based on your financial situation. The core factors that decide a diamond’s price are the famous 4C standards. For most ordinary buyers, diamonds with H color grade and excellent cut are the most cost-efficient option. Under naked eyes, these diamonds look totally clean and shiny without obvious yellow tint. Even if two diamonds own identical 4C grades, there are no two diamonds in the whole world that are exactly the same. Tiny natural differences lead to different price tags for stones of equal grades, so you must check every diamond’s detailed report carefully.

Wedding Diamond Ring

You must stay away from milky, coffee and green tinted diamonds by all means, and never buy stones that look dull and non-transparent. For fancy shaped diamonds like oval diamonds, you need to avoid obvious bow-tie effect which ruins the stone’s beauty and light performance. Meanwhile, skip diamonds with cavity inclusions and other flaws that hurt the diamond’s long-term durability. The 4C system directly decides a diamond’s total value, so you need to choose proper 4C levels matching your own demand and wallet. The 4C rules made by GIA make diamond pricing more transparent for global consumers. Confirming your target 4C standards is like finishing the first big step of your full ring customization journey.

Confirm Your Ring Band Size

Once you select your ideal loose diamond, the next task is confirming the perfect finger size for your ring band. Every person has different finger thickness and length, so one size never fits all. You need to measure your accurate finger circumference to get a suitable size. A easy way people often use is wrapping a thin paper strip around their finger to measure, but this homemade method brings big measuring errors easily. The more precise way is heading to offline jewelry stores and let professional staff measure your finger with standard ring sizers. You can visit two or three different shops to double check your size data before submitting your custom request online.

Wedding Diamond weeding Ring

Besides the size, you also need to pick a proper band width and band style. If the ring band is too tight, it will block blood circulation in your finger and bring constant discomfort. If the band is too loose, the diamond ring may slip off your finger accidentally and get lost easily, which is a terrible loss for any lover.

Choose Your Favorite Ring Band Style

Ring band styles change the whole visual effect of your diamond ring greatly, so you can pick styles based on your personal taste or the shape of your fingers. The market holds countless ring designs with totally different features. Physical shopping malls display many diamond rings, but most of their styles are old-fashioned and out of date. Online custom brands launch much newer, more creative styles for customers to choose. Still, remember the most fancy design means nothing if it does not suit you—only the style that matches you perfectly is the best choice.
You also need to make a decision on stone setting types according to your preference. Some people love simple minimalist designs, such as four-prong setting and six-prong setting, which highlight the central diamond fully without extra decoration. Other buyers prefer luxurious layouts, including cluster setting and halo setting surrounded by small side diamonds to boost the ring’s sparkle.

Free Inner Ring Engraving Service

Nowadays, personalized details become more and more popular in custom diamond rings. Many online jewelers such as James Allen and Blue Nile provide free engraving service for their customers. You can carve meaningful words, special dates, initials or lucky numbers on the inner wall of your ring band. Every time you take a glance at the hidden carving on your ring, warm happy feelings will fill your heart and remind you of your sweet love memories.
After you finish all these preparation steps one by one, you just need to wait patiently for your beautiful custom diamond ring to be manufactured and delivered to your home. When you receive the package and put the ring on your finger, all the time you spend on planning and customizing will feel totally worthwhile.

Diamond Carat: What You Need to Know

Carat is a unit used to measure the weight of gemstones. One carat equals 0.2 grams. The weight unit for gems has changed a lot over time. Since 1913, the whole world has followed the same rule: one carat is one-fifth of a gram.
For small diamonds, one carat is split into 100 points. A 40-point diamond means it is 0.4 carats. Diamonds that weigh more than one carat are much fewer than those below one carat. This is why larger diamonds are more rare and valuable. As one of the four key C factors, carat weight greatly affects a diamond’s price.
Diamonds come in all sizes, from just a few points to dozens of carats. Their distribution is like a pyramid. Diamonds with excellent 4C grades stay at the very top of the pyramid. Here is a simple example. A single 2-carat diamond costs more than two 1-carat diamonds of the same quality. Big diamonds with top-tier cut, color and clarity are really hard to find. One carat is equal to 200 milligrams, and also 100 points.

diamond carat

Carat is the standard weight for diamonds and many other gemstones. It is just like how one dollar has one hundred pennies. A 50-point diamond is 0.50 carats. Two diamonds with the same carat weight can have totally different prices. This big gap comes from their cut, color and clarity. Most diamonds made into fine jewelry are less than one carat. A 1-carat diamond weighs about the same as a paper clip. The higher a diamond’s grade, the stronger the influence of weight on its price.

How Important is Diamond Carat Measurement?

A tiny difference in diamond weight can lead to a huge difference in price. This situation is even more obvious when the weight hits a full carat number. That is why accurate measurement is so important.
In ancient times, different countries used different measuring standards. Back then, one carat was about 205.3 milligrams. To turn it into today’s standard, you need to multiply the old number by 1.0265. The metric carat was officially used worldwide from 1913. Now one carat is fixed at 200 milligrams. People no longer need to do difficult conversions.

carat chart

On official diamond grading reports, the weight is usually recorded to three decimal places. The IGI, International Gemological Institute, uses high-precision electronic scales. Its accuracy can reach 0.00001 carats to get the exact weight of each diamond.

What Carat Size Should You Choose When Buying a Diamond?

Two main things you need to think about first: your finger size and your budget. If you love big diamonds but do not have much money, you should put cut quality in the first place.
Diamonds have carat premium, which means prices rise sharply at full carat marks. Never pick a bigger diamond with a poor cut. A good cut brings out brilliant sparkle and fire in a diamond.
You can also choose diamonds in I-J color grade with no visible flaws to the naked eye. The color difference in this range is hard to notice when you look at the diamond face up. Before you make a purchase, learn well about diamond carat knowledge. It will help you pick out the most suitable diamond for yourself.

Fancy-shaped diamonds

All Blue Nile diamonds are worth buying? 1，Both milky tint and brown hue:Tap to see full diamond info 2，The diamond has milkiness:Click to view detailed diamond information 3，The diamond has medium green fluorescence.:View diamond details 4，The diamond has a cavity:See the diamond details
From the previous article, we learn that diamond quality is mainly affected by the 4Cs, including clarity, cut grade, carat weight and color grade. Among these four factors, cut is regarded as the most important one to decide a diamond’s quality. This conclusion is mainly for round brilliant diamonds, and it does not apply to fancy color diamonds and fancy shaped diamonds.
Nowadays, people pursue more personalized styles, so round diamonds are no longer the only choice. Round diamonds take up about 75 percent of total diamond sales, and the rest market is occupied by fancy shapes. You may wonder what common fancy diamond shapes there are. They include marquise, oval, heart, pear, princess, emerald, triangle, cushion, radiant and asscher cuts.
Most people are familiar with round diamonds. A standard round diamond has 58 facets, while some are designed with 66 or 81 facets. Exquisite cutting skills and perfect symmetry can fully show the brilliant sparkle of a diamond. As for fancy shaped diamonds, you can roughly imagine their looks just from their names. Here is a simple introduction to each classic shape.
The marquise diamond gets its name for its eye-like shape. It is wider in the middle and narrow at both ends. This shape can gather light entering the stone well, so it has nice fire. Besides, it makes good use of the diamond’s weight, so a marquise diamond always looks larger than its actual carat.
Oval diamond is another popular shape. The best length-to-width ratio is 1.5 to 1. It is a great choice for ladies with small or short fingers, as it can make fingers look slimmer. In Western countries, it is favored by people who are creative and have unique tastes.

Fancy-shaped diamonds

Heart shaped diamonds first appeared in ancient India. A standard heart diamond has 63 facets. Its ideal depth ratio is between 59% and 63%, with a 1:1 length-width ratio. Cutting a heart diamond requires extremely high skills from craftsmen.
Pear diamond looks just like a pear, and people also call it teardrop diamond. If you look carefully, you will find it combines the features of marquise and oval cuts. It is widely used for earrings and suits young ladies with a delicate figure.
Princess cut is very common too. It looks like a square covered with many facets, and it normally has 57 to 58 facets. This shape matches ladies who have steady and elegant temperaments.
Emerald cut diamond is in a rectangular form with cut corners, just like a stepped ladder. It can keep more weight from the rough stone. Its ideal length-width ratio ranges from 1.3 to 1.4. Even though it is not as shiny as round diamonds, its pavilion can create special light effects that other shapes cannot match.
Radiant cut is a square or rectangular diamond. It mixes the cutting styles of emerald and round brilliant, so people name it radiant brilliant cut. It is popular among fashion lovers.
Triangular cut diamonds are usually made from flat rough stones. A standard triangle diamond keeps a 1:1 ratio, which helps it gain better brilliance.
When talking about Asscher cut diamonds, many people will think of Queen Elizabeth, who loved wearing this style a lot. Many people mix up Asscher cut and emerald cut. The biggest difference is that Asscher cut is square shaped.
Cushion cut has a classic and vintage style. It owns the advantages of both princess cut and round cut. It is often matched with small accent diamonds to make luxurious jewelry designs.

Why cut diamonds into fancy shapes?

Before cutting a rough diamond, jewelry analysts need to do detailed research. They mainly focus on two key points: getting the highest return on investment and ensuring good sales volume. Careful analysis before cutting is the key to maximum profits. Analysts also need to take other factors into consideration, such as color retention, weight retention, the original shape of the rough stone and the position of inclusions.
There is a famous saying that diamonds are a girl’s best friend. Everyone wants to buy a high-quality diamond at a reasonable price, so it is wise to pick diamonds with Excellent cut grade. James Allen has now merged with Blue Nile. These two brands own a huge inventory of loose diamonds and update the information all the time. If you take time to select carefully, you will definitely find your ideal fancy shaped diamond.

Dimensions of loose 0.7 carat diamond

All Blue Nile diamonds are worth buying? 1，Both milky tint and brown hue:Tap to see full diamond info 2，The diamond has milkiness:Click to view detailed diamond information 3，The diamond has medium green fluorescence.:View diamond details 4，The diamond has a cavity:See the diamond details

I found out recently there are way more customers come to ask about diamonds at around 0.7 carat. Many people got one big question in mind. How big is a 0.7 carat diamond actually? If we set it with a setting that make the stone look bigger, can it show the visual effect same as a one carat diamond ring? Almost everyone who know a little about jewelry know this truth. For diamonds with identical color, clarity and cut grades, a 1 carat diamond cost far more expensive than a 0.7 carat one. The main reason is the carat premium in diamond market. Then here come another doubt. Is a 0.7 carat stone much smaller than one full carat in real sight? Let us take a look at a diamond size comparison picture I prepared below.

Dimensions of loose 0.7 carat diamond

We can clearly tell from that picture. Under ideal perfect cut standard, a 0.7 carat round brilliant diamond has a surface diameter of 5.8 millimeters. On the other side, a standard 1 carat round diamond reach 6.5 millimeters across its top face. The physical gap between these two sizes is really tiny, almost hard to notice with bare eyes. But if you match your 0.7 carat center stone with a well-designed halo or wide open setting which enlarge the stone visually, the whole ring might even looks larger than an original 1 carat diamond ring when people glance at it casually. Just like full one carat diamonds, most qualified 0.7 carat stones will come with international authoritative certificates such as GIA report. Every certified diamond has a unique matching GIA certificate number laser engraved on its girdle edge, so buyers can check the stone identity easily later.
Lots of shoppers have shared same experience with me many times. They walk into some local jewelry store and spot a 0.7 carat diamond there. The store used a simple six-prong mounting for it. Strangely enough, that diamond ring look visibly bigger than the 1 carat rings placed next to it on the display counter. Most buyers will get excited right away when they see such scene. They think they found a super good bargain with huge value. They start wonder should they pay the bill and take the ring home without second thought. Here Ijadiamond give all buyers an important warning, you better stay away from those tricky diamond rings without careful inspection first. Some dishonest merchants use low-quality cut diamonds to cheat ordinary customers, and sell them at high price same as well-cut stones. Those bad-cut 0.7 carat diamonds have an abnormal wide diameter much bigger than official standard data, but their total carat weight still stay fixed at 0.7 carat. To gain a wider table surface, the diamond cutter will make the stone’s pavilion depth extremely shallow. This type of poor cut grade diamond will totally ruin the stone’s light performance and fire. The overall outline of such diamonds just like a flying saucer. People in trade also name them flying saucer diamonds. Do not rush to make purchase decision in such situation. You will lose more money than you save in the end, and the ring will look dull and lifeless forever.

How much money do people need to spend on a 0.7 carat diamond?

Four C standards are the core factors that control all diamond pricing. The four C items include carat weight, color grade, clarity grade and cut grade. If color, clarity or cut grade shift even slightly, the total price of a 0.7 carat diamond can create a massive price gap between different stones. Right now, people can search for 4,349 perfectly cut round 0.7 carat diamonds on the Blue Nile official website. Their price range fall between 11,000 Hong Kong Dollars and 46,800 Hong Kong Dollars. On James Allen’s online platform, there are around 2,956 ideal cut round 0.7 carat diamonds available for selection. Their price start from 10,200 Hong Kong Dollars up to 45,900 Hong Kong Dollars. Online diamond retailers have much lower running cost compare to offline physical jewelry shops. Physical stores need to cover monthly store rent, employee salary, in-store display maintenance and many other daily overhead expenses. Without those heavy extra cost burdens, online diamond shops can offer much friendlier and cheaper price tags for same quality diamonds to all buyers.
