[quote=Anonymous][quote=Anonymous]Are lab diamonds indistinguishable from mined diamonds?[/quote] A gemologist or experienced jeweler can tell the difference if certain inclusions are present. And you can tell the difference with a diamond tester -- lab diamonds do not conduct heat and electricity in the same way mined diamonds do (I believe this is because they form at an accelerated rate, but I'm not sure). But bottom line is going to be that certified lab diamonds are lasered with an inscription on the girdle to indicate they are a lab -- and that is easy enough for just about anyone to see with a loupe. But for anyone who just wants to wear a diamond ring or bracelet or whatever, nowadays lab diamonds are going to be indistinguishable from mined ones if you are just looking down at them on your hand and aren't looking for that inscription on the girdle.
