I saw a documentary years ago on how Debeers controls the diamond market. In it it said General Electric perfected a technique like this and Debeers somehow paid them off. The diamond market has continued. The amount of control Debeers has has slipped but it's still there. Diamonds aren't rare but Debeers has done a wonderful job making the public think they are. I suppose cubic zirconia can be differentiated from diamonds but I think most lay people couldn't tell the difference on first glance. These "real" diamonds should be fun to have soon if this pans out.

It's been illegal to sell (unlabeled only?) artificial gems since 1929. On the other hand, diamond drills are useful.
