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

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.

AGS

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.

IGI

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.

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.

radiant cut

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.

Blue Nile VS James Allen – 哪家才是最好的鑽石公司？

之前聽了一個臺灣朋友的觀點，他認為雖然兩者都是很偉大的鑽戒定制公司，James Allen 比Blue Nile更好一點，原因是james allen做的更人性化，更能以用戶為中心，它的在線網站有豐富的設置和鑽石可供選擇，James Allen還為每一顆鑽石拍攝40X高清視頻。這可以讓顧客以更輕鬆的方式購買鑽石，不用再盯著枯燥的證書和參數，另外從指環工藝上和外包裝上，也可以看出James Allen比較嚴謹。

但是這只是個人觀點，體驗只是當時的狀況，並不能代表所有人的想法，畢竟一千個觀眾眼中有一千個哈姆雷特，bluenile和jamesallen也在改變和成長。我們認為兩家公司都有自己比較好和比較壞的鑽石，如果買到質量好的鑽石，就會認為這家公司比較好，相反如果買到差的鑽石，比如奶咖綠鑽石，瑕疵明顯鑽石，會認為購買的這家公司比較差。 所以要在兩個平臺中挑選品質較好的鑽石，避免踩坑。

James Allen和blue nile也以7*24小時全天候的客戶支持引以為豪，因為他們知道，並不是所有人都對珠寶是十分了解的。如果您是第一次購買結婚鑽戒，可能會輕易地混淆各種參數。 James Allen的珠寶專家總是可以隨時為你提供支持，並在線回答所有的問題或疑慮。James Allen的價格也很有吸引力，與其他當地的珠寶店相比，他們的價格很有優勢。所以，如果你不想在線下商店購買鑽石戒指，那麼James Allen就是一個完美的選擇。您所有的首選都可以輕鬆快捷地找到James Allen定制，因為他們擁有最好的鑽石系列。動態視頻能最直觀地展示一顆鑽石的“火光（Fire）”、“閃光度（Brilliance）”和“閃爍度（Scintillation）”。對於想買到最閃鑽石的人來說，這是必選功能。如果你不看到鑽石的實際樣子就感到不放心，那麼 James Allen 的 360度視頻是無可替代的。這對於檢查淨度特徵（如內含物的位置是否明顯）和切工好壞（看是否有漏光或是否閃耀）至關重要。由於擁有最龐大的庫存，當你需要一顆參數非常稀有的鑽石（例如某個特定的顏色、淨度和克拉數，瑕疵類型，形狀，螢光）時，在Blue Nile更有可能找到它。

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.
