Why Diamond Cut is Important

If you know the first thing about colorless diamonds, you’ll know that cutting is the most important aspect of these stones.

While diamonds are abundantly found in nature, natural gem-quality diamonds are incredibly rare. They are only found in a few places on Earth and thousands of tons of dirt must be moved in order to recover them.  But in their rough state diamonds do not possess the brilliance and fire that make them so mesmerizingly beautiful. Revealing the full potential of their exceptional beauty lies solely in the craftsmanship of the cutter.

To produce a polished diamond with maximum light performance, it must be cut with exacting precision.  A faceted diamond is essentially a sculpture of light with architecture in the form of a system of tiny mirrors.  The precise alignment of those mirrors in three dimensions is what enables a diamond to collect light and redirect it to our eyes in a brilliant combination of brightness, fire, and sparkle that can grab the attention of an observer from across a room. 

Which brings us to the A Cut Above diamond range from Whiteflash.

A Cut Above Diamonds

This range of super ideal diamonds by Whiteflash contains diamonds that are among the best in the world. The crème de la crème, so to speak.

Whiteflash has been pushing the boundaries of cut quality over the last 2 decades and have produced diamonds with light performance at the extreme limits of what is technically possible.

A CUT ABOVE diamonds are meticulously cut and rigorously tested to ensure only the ‘best of the best’ are awarded the A CUT ABOVE brand. 

Each one is owned and kept in-house, and is available for immediate delivery exclusively from Whiteflash.  And each is posted to the Whiteflash website with a comprehensive set of diagnostics including laboratory report, light performance imaging, and 360 HD video. 

A platinum certificate from American Gem Society Laboratories is just the baseline requirement for the A CUT ABOVE brand – an extensive list of additional specifications and qualifications must also be met before the brand is awarded. 

The benefit of this is that all the science and vetting has already been done for you guaranteeing that your diamond will have the optimal combination of properties.

Optical Precision and the Benefits of Hearts and Arrows

The Whiteflash A Cut Above range comes in round and princess cuts. Here are the specifications:


In addition to meeting all required specifications and passing all imaging tests, the A CUT ABOVE® Round must exhibit a perfect pattern of Hearts and Arrows demonstrating that it has been cut to precise three-dimensional symmetry.

Perfect optical symmetry ensures that the diamond is optimally “tuned”, with each tiny facet precisely aligned in relation to all other facets.

This enables the diamond to reflect, refract and return to the eye the maximum quantity and quality of light technically possible.

A CUT ABOVE® Princess

Princess cut diamonds have been one of the most popular ‘fancy shape’ diamonds since their introduction to the market in the 1960s.

With a square shape profile and brilliant style facet arrangement, princess cuts present a wonderful fusion of angularity and brilliance that creates a unique and eye-catching look.

The problem is, most princess cuts are not cut with an emphasis on light performance. Finding a great princess cut is therefore like finding a needle in a haystack.

Most grading labs don’t grade the cut quality of princess cuts. However, the AGS has adapted their sophisticated light performance cut analysis system to grading princess cuts. A CUT ABOVE® Princess requires a triple ideal certificate from AGSL as well as meeting additional Whiteflash criteria in order to be part of the brand.

If you are looking for the best princess cut, Whiteflash has done all the work and has them in stock and available for immediate delivery, for in-store inspection, or for consultation with a Whiteflash gemologist.

A CUT ABOVE® Collection Series

Many shoppers looking for the very best in cut quality are also looking for diamonds of elite color and clarity.  For those buyers the  A CUT ABOVE® Collection Series is the perfect solution – colorless diamonds (DEF), microscopically clean (IF-VVS), and perfectly cut.

Small diamonds are referred to in the diamond trade as diamond melees. Because they are typically used as accent stones rather than feature stones, many people dismiss them as not being very important, especially from a cut-quality perspective.

Whiteflash takes the opposite view – accent stone needs to be cut with precision in order to create the optics necessary for a brilliant piece of fine jewelry. For some designs, they offer A CUT ABOVE® Hearts and Arrows Melee for the ultimate in dazzling sparkle.

This is probably the only diamond retailer to focus on the cut quality of melee diamonds to this extent.

A Cut Above Diamond Price – Are They Too Expensive?

It goes without saying that the A Cut Above the diamond line is among the best in offering top-quality diamonds. And this of course reflected in the price, as it’s their most expensive line. If you’re looking for a budget diamond, then, needless to say, this probably isn’t the best diamond collection to be looking through.

However, to put this in perspective, you could compare one of these diamonds to any diamond that you find at a big brand store like Tiffany, Cartier, or Harry Winston. The Whiteflash A Cut Above diamond would be equally beautiful (if not of better quality) but with a significantly lower price.

When comparing these exceptional Whiteflash diamonds, you have to compare them to other high-end diamonds as that is the category that they fall in. You might not find them high in price.
