Hi! I’ve read articles on the two lab methods, but I’m looking for more anecdotal information. Does the method affect sparking?
CVD is mine originally formed as a cube – does it make it easier to get an ideal cut? On the other hand, HPHT has more sides than a natural diamond, so they would probably reflect even more light!
CVD only produces type IIa diamonds..HPHT does not .. they are mostly not IIa and usually more yellow.
But the general idea I gather from info is that CVD is better, but that people have a bias against it. Why?
Thanks for all the thoughts!
