Product Description
Large Size Carat Uncut CVD Hpht Synthetic Lab Grown Rough Diamonds
Our lab-grown diamonds are produced by HPHT cubic press machine, just as the photo showed, this is the process of diamond producing, in order to realize the best production capacity,the operator adjusts the parameters of diamond growth by using an electronic control system.

Lab-grown diamonds have the same chemical charactoristics with natural diamonds, and compared with natural diamonds, it's more economy-effective and environment-friendly, so the market for lab-grown diamonds is expanding.

CVD diamonds are produced by chemical vapor deposition, and HPHT diamond means using high temperature and high pressure machine to simulate the process of crustal movement growing diamonds.Compared with CVD diamond, the production cycle of HPHT diamond is shorter and the yield is higher, meanwhile, the color of the HPHT diamond can almost reach D,E,F color, which is better than CVD diamond.
The process of diamond production:

1. Preheating preparation;

2. Put the synthetic block, and find the temperature field, according to the crystal performance to confirm whether the pressure and temperature are appropriate;

3. Check the specific synthesis situation;

4. After confirmation, put synthetic block and complete diamond growth;

5.Finally, the diamonds will be acid-washed, sorted, registered and stored.
