DIAMOND / GEMSTONES

Diamond jewelry is now more popular than ever.

In the past few years the global market for diamond crystals has grown by five percent annually. This is partially attributable to the growing demand in the USA, Asia and India.
Because natural resources are limited and the exploitation is associated with great burdens on people and the environment, “man-made” diamonds are getting more important.

With plasma-assisted CVD processes single-crystal diamonds can now be produced in considerable numbers and thus at an attractive cost.
The synthetically produced crystals are in no way inferior to naturally occurring diamonds in terms of purity and transparency – even red, green or blue coloration is possible.

Diacara will advise you with respect to best microwave-based CVD technologies for growing diamond, applying multiple-seed growth for enlarging the yield and the use of correlated techniques like laser-cutting and polishing for harvesting and shaping. In addition, we are experts for identification and characterization.
