Top colors and clarity from the best rough

We use only specially-selected, premium grade American rough from Ceres Crystal Industries Inc. of Niagara Falls, N.Y., which is the best in the industry. They were the first guys who made it in the U.S. and still continue making it now.

Top brilliance from precision cutting

With our computer-designed preforming cams, our stones of the same shape and size will be exactly the same in contour. We utilize angle-index cutting machines. Our cutters use 10x-loupes in every step of the cutting. We also devoted ourselves to the use of finely graded 0.25-0.50 micron size (the finest available) synthetic industrial diamond powder for the time-consuming final hand-polishing, resulting in our renowned exceptional "adamantine polish". With the uncompromising perfection-oriented 3 stages quality control, customers can be sure that every single stone is precisely perfect.

Ease of use

The identical 3-dimensional geometry of the stones of the same shape and size, together with the size tolerance of +,- 0.10 mm. in stones without points (e.g.rounds, ovals etc.) and +,- 0.2 mm. in stones with points (e.g.marquises, pears etc.), allows faster setting with much less damages.
