This was due to the actuality that it took abounding years for General Electric to aftermath a constructed design that could analyze with the affection of a accustomed design – and back they ample out how to do it, they begin that it amount added to aftermath a constructed design than it did to abundance and cut accustomed diamonds.

Finally, a baby aggregation by the name of Gemesis Corporation ample out a way to aftermath constructed chunk that were of the aforementioned affection as accustomed diamonds, at a cheaper price. Today, Gemesis produces constructed white diamonds, and black chunk as well. These chunk advertise for about 1/3 of the amount of a accustomed diamond, but there is a curtailment of them, and they are adamantine to find.
