The Ever Growing World of Diamond Cuts

Learn about the most popular diamond cuts today

The world of diamonds is one of great history and ever growing creativity, with the thought of achieving perfection directing the creation of new cuts, and the improvement of existing ones. Below is a list of some of the most popular diamond cuts known today.

Round Brilliant Cut

In 1919 Marcel Tolkowsky introduced the original round brilliant cut. Since then the cut has progressively improved to optimize its fire and brilliance. The goal is for the light to reflect back to the eye from the center of the table. As of today the round brilliant cut diamond is the most popular diamond shape, and for a good reason..

 The Round Brilliant Diamond is the most expensive shape.  For instance, a diamond with the same carat weight, color and clarity will roughly cost around 20% more compared to another shape, with the identical specs. Another reason that the round brilliant shape is more expensive is that in order to achieve a perfect cut you’re required to lose more of the rough material in the process of cutting the shape. Of course, there’s also the fact that diamond prices like everything else, are also effected from supply and demand, and the round shape is the most popular at this time.

 One of the oldest diamond cutting shapes that regained popularity in the last decade. Back in the 17 century this cut was named “old mine cut” and was common until the 19 century.

The modern cushion cut diamond has improved leaps and bounds to create a more brilliant end product with more “fire”. The Cushion can be cut to square or rectangular.

The oval cut diamond is  an elongated shape filled with elegance.  It contains a larger surface area compared to its ancestral round cut, which gives the appearance of being larger.  It is one of the only alternatives to the classic brilliant round cut that is able to match its sparkle and beauty. It is also more affordable due to being less popular compared to the classic round cuts, but then again, no cut is more popular than the round.  All this adds to its overall appeal as an alternative piece.

Emerald Cut

The Emerald Cut, also known as the octagon cut, due to its octagonal outline, is the most popular of the fancy shapes family. The classic proportion between the length and the width is 1.35 but can be up to 1.50 ratios. When we set Emerald cut stones in a layout,their larger ratio provides the effect of looking bigger. The choice of rough material used has to be planned ahead. Ideally, a piece with as little imperfections as possible, and good clarity, as the Emerald brings both the good and the bad into light.

However, in order to truly present a convincing heart shape, the symmtery must be impeccible, most notably between the top arches.

The reason however, that the Marquise Cut remains popular to this day is due to its unrivaled feminine quality, and flattering asthetics.
