The diamond/gem stone mining industry has worked intensely to denigrate lab grow minerals/gem stones. Lab grown gems can be grown very precisely and to the highest grades. But the industry propaganda would have retail jewelry buyers believe that lab grown gems are not even real gems since they weren't found naturally occurring in ground. Humans are silly animals. Jewelry industry itself to me is ridiculous. Just say no to high prices for jewels and gemstones and colored mineral glass. Great for industrial application and that is all. For decoration it is just simple unarguably stupid. (only my opinion of course)
Synthetic DIAMONDS are already very inexpensive and it's just a matter of time before their availability overwhelms expensive mined diamonds. I expect diamond mines will begin to be abandoned by 2014 and shortly thereafter the rest will close forever.
