a company called Gemesis does the same thing but they make nice looking real diamonds that cost only quarter of the price.. as opposed to 15% less..

@NeoQuello Thanks for the comment. I have several videos on Gemesis diamand on my channel, so I am quite aware of them. As far as I know, their process does not take the steps to remove nitrogen from the atmosphere surrounding growth chamber. As a result, all Gemesis are yellow diamonds. The Apollo process can produce any color including the colorless diamonds by controlling what "contaminants" are allowed in the growing process.

So what makes this stone different from a Cubic Ziconium (sp) aka CZ & why ? Other than cost

[cplai]

Diamond is a crystal of carbon element. Cubic Ziconia is a compound of Ziconium that display similar look and feel, but not exactly, CZ is made to fake a diamond. A simple test will tell between the two. Cultured diamond is NOT fake diamond, it is a man-made real diamond. Not from the ground, but from a lab. Since lab condition can be tightly control, it may be possible that cultured diamonds can be made flawless, unlike mined diamond.

@zzap999. Thanks for the info. Btw, personally, I prefer the CZ.

b/c the average person doesn't know the difference, particularly when it's a believable size. I've seen some beautiful CZ's. Just saying.

@zzap999. Are these Lab Diamonds being accepted in the Matket Place/retail industry? I saw a documentary some yrs ago about how the de beers family will buy inferior diamonds @ premium prices, all in an effort to keep the supply down, thus, keeping the cost elevated; you know the Law of Supply and Demand. I also read an article that states their once 90% Markert Control has slipped down to 40%.

[zzap999]

@esquireyes All I know it's less based on what I hear on t.v . I've never gone to an actual diamond store to ask. The gaps are probably due to the fact that even lab diamonds vary in quality like natural diamonds. Some sparkle more than others.

[esquireyes]

@zzap999. How much less does the Lab Diamonds cost than the Mine Diamonds? The percentage, that is? I Googled this question & got a big gap in the percentage?

[zzap999]

@esquireyes Lab diamonds by Gemesis and Apollo are real diamonds. They take a real seed diamond and sprinkle carbon atoms on top either through pressure or gas vapor. A thicker formation of crystallize carbon forms on top. The result is a real diamond. After all, a diamond is just crystallize carbon atoms. DeBeers has tried to get the world to call them synthetics. However, they are called and graded as diamonds by the experts. "Cultured" is another term used.

[esquireyes]

@zzap999. I know that "only" a real diamond can cut another diamond & that's why I find this confusing b/c this is a Lab Diamond (man made/fake) & that's "not" a real diamond. So, how can a Lab Diamond (fake diamond) cut a mine diamond (real diamond)? Real diamonds come from mines, "not" from labs. Peace.

[zzap999]

@esquireyes Lab diamonds can cut a mined diamond because it's real. The fake diamonds will get detroyed if it every rubbed against a real diamond. Only a diamond can cut another diamond.

@cplai

there are flawless diamonds, and these are mined. quite rare but D-color (whitest white) internally flawless diamonds do exist. right now its not possible to create such a diamond in the lab, lab diamonds always have some impurities. often they manage to make diamonds where the inclusions are so few and so small that only a very good microscope can detect them, and the stone is eye-clean.
