Bought a 2.57 carat E VVS1 Ideal Lab Grown. Trying to understand the cost potential cost effects of HPHT versus CVD

Hello everyone,

Hope to lean on the wisdom of the community here. I bought a lab-grown diamond from James Allen and found one that stood out from the rest in terms of cost. The diamond I chose (highlighted) has lower prices and higher carats, and in some cases clarity than diamonds with similar prices. Because of these reasons, I felt confident that I should pull the trigger.

When I received the diamond, I reviewed the IGI certificate and noticed that it was created through the HPHT process. Digging further, I realized that there is another process, CVD, that produces a more carbon pure diamond (IIA) than the HPHT process. This aroused my interest and I researched further and found that an HPHT diamond can be magnetic and potentially a diamond tester fails.

*** Is it possible that the method used to create a laboratory diamond has a significant impact on costs? *** Is that why the diamond was significantly cheaper, or did I really find “A diamond in the rough”. I spoke with James Allen customer support and there is currently no way for a consumer to get information about the diamond’s production method before buying it. When you request certifications from them, they email you a PDF with the certification, but it lacks that part of the CVD or HPHT list. They also explained that most of their Lab-grown diamonds are made through HPHT.

In any case, I would say that after examining the diamond in person, the particular eye test consists and looks good. I think I’m sticking with my purchase, but I wanted to reach your gurus while the 30-day return policy is still active.

Thank you, everybody!
