A diamond certificate is like a diamond’s ID card. Blue Nile and James Allen were once two of the world’s top online diamond retailers. Here is a new update: James Allen is now part of Blue Nile. Their diamond inventories have fully combined together. When it comes to diamond documents, the most well-known and reliable ones are from GIA, IGI and AGS. AGS have much stricter rules for diamond cut grading.

GIA Certificate (The Most Important One)

Both Blue Nile and James Allen highly recommend natural diamonds with GIA certificates, especially for stones over 0.5 carats. GIA is the most strict and trusted lab in the jewelry industry. The famous 4C standard for diamonds was created by GIA. Diamonds with GIA papers use unified grading rules. They are easy to compare, and also hold their value better over time.

My shopping advice: No matter where you buy diamonds, always pick those with GIA certificates first. It is the best way to aviod confusion and guarantee real quality.

What is AGS Certificate?

AGS stands for American Gem Society. It is an organization that protect consumers and share professional jewelry knowledge. AGS Laboratories issues official diamond grading reports, known as AGS certificates. This lab earn great fame for its advanced cut grading system. AGS is highly authoritative. Its cut evaluation is widely seen as one of the most precise in the trade. AGS enjoys the same good reputation as GIA, and both are top trusted diamond certificate providers.

IGI Certificate

Both retailers also carry diamonds with IGI certificates. IGI is extremly popular in the lab-grown diamond market, and its standards are widely accepted around the world.

Blue Nile keeps a large stock of natural diamonds with IGI certificates. Customers need to check the certificate type carefully when making choices.

In-house or Other Commercial Certificates

For tiny diamonds below 0.5 carats, or finished set jewelry, both brands may use their own in-house certificates or other commercial papers.

Important warning: You need to be very careful with these diamonds. In-house grading standard are not as strict as GIA or IGI. Grade inflation often happen here. For example, a diamond graded SI2 may be marked as VS. Ordinary buyers can hardly tell the real difference.

Shopping tip: Try your best to stay away from diamonds with only in-house certificates. Only choose them if you fully trust the brand or you have a very tight budget. Stick to GIA or IGI certificates to keep yourself safe.

Visual Technology (Great Helper for Online Shopping)

Both platforms own excellent online video tools. Blue Nile provides 360° high-definition videos for every single diamond. With the free real-time inspection function, you can zoom in, rotate and check every facet closely. You can clearly see the exact position of inclusions and how serious the bow-tie effect is. This experience is almost the same as viewing the diamond in person.

Final Reminder

Always stay alert. Do not buy diamonds that only come with seller’s own certificates, without GIA or IGI reports. New buyers should skip these items, unless the price is really attractive and you are willing to take the risks.

Radiant shape diamond

The radiant cut was invented by diamond cutter Henry Grossbard in 1977. At that time, he wanted to create a new diamond cut. It should keep the elegant outline of emerald cut, and own the brilliant fire like round brilliant cut. This design became an important innovation in the history of diamond cutting. The radiant cut is a mixed style. It combines the strong sparkle of round brilliant cut and the elegant shape of emerald cut. Today, it is widely loved for its bright shine and modern look.

Main Features of Radiant Cut

Mixed Cutting Style

The crown uses multi-facet design similar to round brilliant cut. It usual has around 70 facets. These detailed facets reflect light to the fullest. They bring amazing fire and brightness to the stone. The pavilion also adopts brilliant cut, which further boost light refraction and sparkle. The beveled facets on the crown are the most typical mark of radiant diamonds.

Outline Shape

A radiant diamond is a truncated rectangle or square. Its four corners are cut flat. This design is not only beautiful, but also very practical. The flat corners protect the diamond well. It is much harder to chip or crack than emerald cut or Asscher cut diamonds.

Visual Performance

Different from step-cut emerald diamonds, the rich facets of radiant cut can hide internal inclusions very well. So buyers do not need to chase super high clarity grade. Besides, its special cutting proportion makes the table look larger. A radiant diamond often appears bigger than a round diamond with the same carat weight. Long rectangular radiant diamonds also work well to slim down fingers when worn.

How to Choose a Radiant Cut Diamond

There are several key points you need to check.

Length-to-Width Ratio

This ratio decides the overall shape of the diamond.

For square radiant diamonds, the ideal ratio is between 1.00 and 1.05. It looks neat, symmetrical and modern.

For rectangular radiant diamonds, the common range is 1.15 to 1.50. It shows a longer and more traditional style. You can pick the shape based on your own taste.

Cut Quality

Cut is the most important factor for radiant diamonds. A good cut makes the stone shine brightly. A poor cut will make it look dull. You need to check symmetry first. All facets and cut corners should line up evenly. Polish is also important. Smooth surface guarantees good light reflection.

Almost all radiant, oval and marquise diamonds have the bow-tie effect. It means dark bow-shaped areas inside the stone. You must pick diamonds with faint or nearly invisible bow-tie marks. It is best to check the real stone or related videos by your own eyes.

Color Grade

Radiant cut can mask slight yellow tones well. You can choose a slightly lower color grade than round diamonds. G to H color and above are popular choices with great value for money.

Clarity Grade

Thanks to dense facets, inclusions are easy to cover. VS2 and SI1 clarity are safe and cost-effective choices. Just make sure no obvious inclusions sit right under the table or ruin the overall look.

Carat Weight

Select carat according to your budget and preference. Since radiant diamonds look larger visually, a smaller carat radiant may look as big as other fancy cuts with higher carat.

Advantages of Radiant Cut Diamonds

It delivers outstanding fire and brightness, extremely sparkling.

It has a unique modern geometric shape, fashionable and timeless.

Truncated corners prevent damage, so it is durable for daily wear.

It hides inclusions effectively, so the requirement for clarity is lower.

It looks visually larger than other cuts at the same carat.

Disadvantages of Radiant Cut Diamonds

The unavoidable bow-tie effect needs careful selection.

Cut quality greatly affects appearance, so you need professional knowledge or trustable sellers.

It is less classic and resale valuable than round diamonds, though more popular than most other fancy cuts.

Since cut quality and bow-tie effect matter so much, we strongly suggest you view the real diamond in person. You can also buy from reliable sellers who provide high-definition 360° videos. You may read customer reviews from Blue Nile and James Allen, which two brands have merged now. In this way, you can make sure the diamond meets all your expectations.

Fancy-shaped diamonds

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.

Diamond Q&A

Diamond Selection Advice for $2000 Budget on Blue Nile

Post author By Review
Post date May 25, 2017
No Comments on Diamond Selection Advice for $2000 Budget on Blue Nile

Customer: Hello there. I am planning to purchase a diamond engagement ring recently. I have spent time learning the basic knowledge of the diamond 4Cs grading system and fundamental reading skills for GIA diamond certificates. I have browsed hundreds of loose diamond listings on Blue Nile’s Hong Kong website for quite a while, yet I feel totally overwhelmed by countless options now. My biggest worries are accidentally picking dull stones with obvious visible flaws that lack sparkle. More importantly, I am extremely concerned about purchasing milky, brown or green-tinted diamonds, commonly known as milk, coffee and green stones. These problematic visual traits cannot be filtered out through Blue Nile’s built-in parameter filters at all. Besides, I still lack professional know-how to thoroughly interpret every detail on a GIA certificate on my own. Could you offer me professional diamond selection guidance and help screen cost-effective loose stones that avoid all the above risks? I would really appreciate your professional advice.

Ijadiamond: Hi. I totally understand your concerns. Unfortunately, neither milky haze, brown/green tint nor eye-visible blemishes can be identified merely from GIA certificate data. All these undesirable optical features can only be judged by examining the physical diamond in person, which creates a natural limitation of online diamond shopping. Even though Blue Nile provides 40x magnified footage for every loose diamond listed, these digital materials still cannot fully replicate the true visual performance of the stone. Therefore, the standard and reliable solution is to shortlist qualified diamonds with ideal 4C parameters first, then submit the serial numbers to Blue Nile’s customer service team. You can ask their gemologists to manually inspect the actual diamond samples and confirm whether there are milky, brown or green undertones before you place an order. This double-check process effectively lowers your purchasing risks.

Customer: That makes perfect sense. My total budget is around 2,000 US dollars. Could you help me find a 0.6-carat round loose diamond with VS2 clarity or higher grading, alongside well-balanced table percentage, depth percentage and ideal proportion parameters for maximum light reflection? Thank you so much again for your patient guidance.

Ijadiamond: Take a look at this first option: https://www.bluenile.com/hk/diamond-details/LD08522774. It carries VS1 clarity, outperforming your minimum VS2 requirement, and all proportion metrics reach premium levels for outstanding brilliance. Another great alternative from Blue Nile’s inventory is this listing: https://www.bluenile.com/hk/diamond-details/LD08377103.

I also recommend one high-quality stone from James Allen, which has merged with Blue Nile under Signet Group: https://www.jamesallen.com/loose-diamonds/round-cut/0.66-carat-h-color-si1-clarity-excellent-cut-sku-2534596. Even though its clarity grade is SI1, the flawless stone is completely clean to the naked eye and boasts an Excellent cut that delivers exceptional fire and sparkle.

Customer: Thank you for the recommendations. How about this diamond I found earlier? It also looks pretty attractive to me: https://www.bluenile.com/hk/diamond-details/LD08727381

Ijadiamond: This loose stone is also a solid pick with a superior color grade compared to many similar options. The only downside is its price tag is slightly higher than your target budget range of $2,000.

Customer: Got it, I will compare all these four stones carefully and finalize my choice among them.

Ijadiamond: Wonderful choice! I am looking forward to seeing photos of your finished diamond ring once you receive it.

Shared Core Features of James Allen and Blue Nile

Business Model: Both brands run online-focused sales systems. Online operation greatly cuts operational costs, so their prices are generally cheaper than physical jewelry stores.

Blue Nile was founded in 1999 by Mark Vadon. He built this online diamond brand out of dissatisfaction with the poor shopping experience in offline diamond boutiques. Blue Nile runs a pretty straightforward business strategy: they sign exclusive supply contracts with diamond wholesalers, which limits those suppliers to only sell their diamonds through Blue Nile’s channel. However, buyers often face frequent stock shortages of popular diamond specifications, this situation shows Blue Nile has relatively weak controlling power over its diamond supply chain. James Allen created a totally new operating mode for online diamond sales. They arrange global suppliers to keep their stones stored near James Allen’s New York office space. Under this arrangement, James Allen’s staff can easily visit supplier warehouses and shoot high-definition video footage for every single loose diamond they supply.

James Allen’s website adopts modern, intuitive page layout, users can filter and browse diamonds effortlessly, paired with high-definition stone videos to deliver top-tier shopping experience.

Blue Nile’s official site packs powerful filtering functions with super detailed parameter options, but its overall interface design looks a little more old-fashioned.

Blue Nile VS James Allen: Which Diamond Brand Is Truly Better?

I once talked with a friend from Taiwan who shared his personal opinion on these two brands. He admitted both are outstanding custom diamond ring retailers, but he thought James Allen outperforms Blue Nile slightly. His reasoning was that James Allen designs its service system with stronger humanization and genuine user-centered logic. Its official website carries rich filter tools and countless diamond options, plus every single diamond gets a dedicated 40X HD video shot by James Allen’s team. This function lets customers shop with far less stress, instead of staring at dry, complicated certificate parameters for hours. Apart from viewing footage, James Allen also shows stricter standards in ring craftsmanship and product outer packaging.

Nevertheless, this is just one personal subjective judgment, and the shopping experience he received only reflected the brand’s status at that time, it cannot represent all consumers’ thoughts. Just as the old saying goes, a thousand readers have a thousand versions of Hamlet, Blue Nile and James Allen keep updating and upgrading their services all the time. Now these two brands have merged into one single group, and both platforms carry diamonds with mixed quality levels. If a buyer picks a well-cut, clean stone, they will naturally praise the brand, on the contrary, customers who receive cloudy, milky, green-tinted diamonds or stones with obvious noticeable flaws will hold negative views against the brand they bought from. For this reason, shoppers still need to screen diamonds carefully on both platforms to avoid low-quality defective stones.

Both James Allen and Blue Nile take pride in their 24-hour all-day customer support teams, because their management fully understands most ordinary buyers lack professional jewelry knowledge. If you purchase an engagement diamond ring for the very first time, you might easily get confused by various diamond grading parameters. James Allen’s certified gem specialists stay online around the clock to answer all your questions and resolve any shopping worries. Its price tags also hold strong advantages compared with local offline jewelry boutiques. If you refuse to shop diamond rings at physical stores, James Allen will turn out to be your ideal shopping destination. You can finish all your custom ring demands quickly and smoothly on James Allen’s website, supported by its complete, premium diamond collection. Dynamic diamond videos display three key light performance features directly: fire, brilliance and scintillation. This viewing tool is a must-have function for anyone chasing the sparkliest diamonds. If you feel uneasy buying a stone without seeing its real visual performance, James Allen’s 360-degree video function has no equal alternatives. It plays a critical role for buyers to check clarity characteristics such as obvious internal inclusion positions and cut performance, including light leakage issues and overall sparkle levels. On the other hand, Blue Nile’s unmatched massive inventory makes it much easier to locate diamonds with extremely rare parameters, such as unique color grades, specific clarity and carat weights, special flaw types, uncommon stone shapes and customized fluorescence levels.

How to choose diamonds with high cost performance

Most people buy diamonds for daily wear. In daily life, the first impression others get from your diamond is its size and sparking shine. For clarity grade, you can pick SI1 or SI2 stones that look clean under naked eye. For color, H color is the best choice with great value. If you plan to buy big diamonds above 1.5 carat, VS2 clarity and F, G color will be more suitable. But cut grade must be 3EX without any exception, only this grade can make your diamond shiny enough. Because even within Excellent cut grade, there still have good and bad cutting craft. Bad cut will heavily damage diamond fire and sparkle. You can leave message in the question column on right side to contact us for more professional selection advice. The diamond introduce below have really good cost performance, friends who like it don’t hesitate to place order quickly.

One important rule you must keep in mind: High cost performance do not equal cheap price. It means you spend the most reasonable budget to buy the most beautiful looking diamond. When you wear a diamond ring on your hand, almost no one will check its certification report. People only notice how shiny, white, bright and big your diamond look. You need to make the smartest choice within your planned budget.

Four core shopping strategies for cost-effective diamonds

1. Cut is the most important factor, never save money here

Cut directly decide whether your diamond sparkle or dim. Even if a stone have perfect color and clarity, bad cut will make it look dark and lifeless.

How to select suitable cut?

Shape: Round brilliant cut have the best shine, but it also cost the most. If you want higher value for money, fancy shapes like Cushion, Oval, Princess Cut and Radiant cut worth your consideration. These fancy diamonds usually carry lower price per carat.

Grade standard: Only pick Excellent for round diamonds, Very Good is acceptable for fancy shapes. This is the last standard you should compromise. For round stones, GIA certificate is your top priority choice.

Proportion: Refer to proportion data on your GIA report and pick stones fit standard range, for example table percentage 54%-58%, crown angle 34-35 degree. These numbers guarantee outstanding light performance.

2. Color: Make proper compromise, human eye hard to tell small color gap

Diamond color grade range from D to Z, yellow tone grow heavier as grade drop. But after certain level, naked eye can hardly tell color difference, while the price gap between grades is huge.

G, H, I color are great options. When set on ring band, these three grades look pure white to most people, and their price much more affordable than D, E, F top white color.

Inlay trick: If you choose I or J color diamond, match it with rose gold or yellow gold setting. The warm tone of precious metal can neutralize slight yellow tint on stone, make diamond look whiter visually.

3. Clarity: Stone clean to naked eye is perfect enough

Why we can relax on clarity? All clarity grades judge under 10x magnifying glass. Many tiny inclusions can not be seen by bare eyes at all, and choosing such stone can cut down lots of your budget.

VS1, VS2 and SI1 are recommend grades. Inclusions inside these stones are invisible to most people, price far cheaper than VVS series.

You need extra caution when select SI1 diamonds. You must watch real stone or 360 video to check two key points: first, inclusions should not sit right at center of diamond table; second, avoid stones with big black crystal or obvious feather crack.

Better stay away SI grade diamonds with heavy cloud inclusion, these stones may turn out to be milky diamond with low transparency.

4. Carat weight: Take full advantage of weight threshold price gap

Diamond price jump sharply at whole carat marks like 0.5ct and 1.0ct, this is called carat premium.

How to save cost on carat?

Choose stones just below whole carat line: pick 0.9 carat instead of full 1.0 carat, choose 0.45 carat rather than 0.5 carat. The visual size difference is tiny, but you can save a large amount of money.

Pay attention to diamond diameter mm number on certificate. A well-cut 0.9ct diamond may look same big or even larger than a poorly cut 1.0ct stone.

Standard parameter list for a ideal cost-effective diamond

Shape: Round brilliant or fancy cut (Cushion / Oval)

Cut grade: EX / VG (certified by GIA)

Color grade: G / H / I

Clarity grade: VS2 / SI1 (must pass naked eye clean test)

Carat weight: 0.9ct, 1.2ct, 1.8ct (skip full whole carat number)

Fluorescence: None or Faint. Strong fluorescence will lead to big price discount. If you do not mind cloudy look under UV light, sometimes you can buy high grade diamond at extremely low price.

Certification lab: Only trust authoritative labs like GIA, IGI or AGS. Other unknown small labs have loose grading standard, it is not wise to pick their report just for lower cost.

First figure out your top priority: Do you chase bigger size? Whiter color? Or maximum sparkle? Then use the above cost-performance rules to filter stones on online diamond search platforms, including James Allen, Blue Nile, Brian Gavin Signature Diamond and Whiteflash. For all candidate stones you filtered out, watch their high-definition 360 real stone videos carefully, compare sparkle level, inclusion position and actual color tone one by one. A high cost performance diamond means excellent cut, properly compromised color & clarity (clean to naked eye), weight skillfully avoid whole carat threshold. Diamond certificate exist to guarantee authenticity and accurate grading, but your own eyes are the final judge for visual beauty.

Massive diamond inventory online bring customer abundant choices, but all online stores also have obvious drawbacks. The core problem is uncontrollable stone condition. All loose diamonds they sell source from diamond suppliers all over world, store staff never see the real stone before put it online for sale. This problem become worse for low clarity diamonds. Suppliers want to sell these stones as fast as possible, so they always give vague, evasive answers when customer ask for naked eye inspection details. This is the direct reason why many buyer get disappointed after receiving cheap low-clarity diamonds they bought online.

But every online store have both high-quality and bad quality diamonds, thousands of customer still buy satisfying stones through internet shopping. Our team have professional experience to pick premium diamonds, we will skip milky stones and diamonds with obvious visible flaws. Feel free to leave comment below if you have any questions.
