Whiteflash Certified Diamonds

Whiteflash features four categories of natural Earth-mined diamonds including three in-house brands of owned inventory, fully vetted, analyzed, and ready for immediate delivery. In addition, we also offer top quality laboratory grown diamonds. A brief description of each category is provided below, with links to more in-depth information.
Whiteflash offers more in-stock ideal cut diamonds in the most desirable sizes and qualities than any other retailer. These diamonds are posted to the website with a comprehensive package of diagnostic images including 360 HD video, and are available exclusively at Whiteflash. All in-house natural diamonds also feature our popular 100% Lifetime Trade-up Benefit, in addition to our industry-best assurance package.
At the pinnacle of our natural diamond offerings is the incomparable A CUT ABOVE® Super Ideal in both Round Hearts and Arrows and Princess Cut. These are the ‘best of the best”, and internationally recognized as being among the finest diamonds ever brought to market. Whiteflash is the developer and sole distributor of A CUT ABOVE® diamonds.
Just below our Super Ideal brand sits the Expert Selection category. Expert Selection features diamonds with ideal light performance that may have narrowly missed making A CUT ABOVE® for technical reasons. And our Premium Select brand features diamonds of outstanding quality and value.
In addition to our in-house diamond brands, Whiteflash offers a wide variety of other available diamonds in other shapes, sizes and price points in our Other Diamonds category. We never drop ship, so each diamond we offer undergoes thorough gemological review before shipment.
As a modern counterpart to our selection of natural Earth-mined diamonds, Whiteflash now offers best-of-class lab grown diamonds in our Precision Lab category. We leverage our expertise in diamond cut quality and light performance to present only the finest precision cut lab created diamonds, with the full set of diagnostic reports and light performance images for our customers to fully understand these precision cut diamonds.
As one of the few retail jewelers in the world certified for ISO 9000 Total Quality Management, we strive to give our customers a full range of options and total confidence in their diamond purchases.

Our A CUT ABOVE® brand is a globally recognized Super Ideal and consists of both round and princess cut diamonds. Rounds are cut to a narrow subset of AGS Ideal specifications and feature perfect Hearts and Arrows patterning and Optical Symmetry. Hearts and Arrows images are posted to the website for all A CUT ABOVE® Round Super Ideal Diamonds. A CUT ABOVE® Princess diamonds are screened for any issues that may compromise light performance or durability. Because the precise facet configuration of the princess can vary, expert visual evaluation further ensures superb aesthetics.
In order to achieve the A CUT ABOVE® designation, a diamond must first receive the coveted Platinum Triple Ideal certificate from the American Gem Society Laboratory (AGSL) - the ultimate cut quality pedigree from the most stringent gemological laboratory in the world. In addition, candidates for the A CUT ABOVE® brand must pass a host of additional evaluations including light performance imaging tests and physical examinations by a panel of Whiteflash gemologists. Whiteflash is the only company to publish the exact qualifications and specifications of the brand.

A CUT ABOVE® Collection Series

The ultra-elite subset of our super ideal brand is the A CUT ABOVE® Collection Series. Diamonds in the colorless range (DEF) and either Internally Flawless or with only microscopic inclusions (IF-VVS), are at the pinnacle of rarity. When combined with super ideal precision cutting, they are the highest performing and most beautiful diamonds in the world.
There are cultural, emotional, and rational reasons why these diamonds are desirable and sought after. While the price premium is significant, when it comes to diamonds many buyers want nothing less than the very best that money can buy.

Expert Selection

The Expert Selection category features AGS certified ideal cut diamonds of outstanding quality. As the name implies this is a very select collection of diamonds possessing outstanding light performance and exceptional beauty. Many diamonds in our Expert Selection category narrowly missed the stringent requirements of our A CUT ABOVE® Super Ideal brand.
In addition to having the highest cut quality grade awarded by AGS Laboratories, Expert Selection diamonds must have Hearts and Arrows optical precision.

Premium Select

The Premium Select category can be thought of as the GIA version of Expert Selection.
As the name suggests, the diamonds in this category are of premium quality. In order for a diamond to qualify as Premium Select, it must have the top grade for cut quality awarded by GIA - Triple Ex. In addition, rounds in this category also must possess optical precision to a level exhibiting distinct Hearts and Arrows patterning.
