Precise Brilliance

We make lab grown diamonds. Over the past 15 years we have perfected the process of creating created diamonds.

The process is simple but the equipment and materials are sophisticated. Diamonds are made from a combination of heat, pressure, carbon, and time we have essentially created the same elements in which diamonds naturally develop when they form in the earth's crust but in a controlled Eco-friendly laboratory.

EX3 Diamonds have the same crystal structure, brilliance, and weight of earth mined diamonds the only difference is one was made from earth the other in a laboratory. The end result is the same. Down to the last atom EX3 lab grown diamonds are 100% diamond.

Skillfully Finished

The rough tetrahedron carbon rock is faceted and polished into a sparkling diamond.

We follow strict ideal cutting standards, while maximizing total diamond weight. Cut is the one aspect we scrutinize. Cutting ensures the diamond has maximum sparkle and brilliance.

We have several skilled cutters, one of our master cutters studied Tolowksi who was the inventor of the "ideal" cut dimensions, among other contributions to the diamond and jewelry business.



All of our loose lab grown diamonds have been tested, analyzed, examined, and laser inscribed by International Gemological Institute (IGI). Lab grown diamonds are physically, optically, and chemically indistinguishable from natural diamonds.

Using professional gemological equipment, lab grown diamonds are almost impossible to differentiate from natural diamonds. They can only be identified with extensive scientific testing using specialized equipment.
