The GE diamonds are industrial grade and they have been
making it for a long time. If I remember correctly, a
Frontline program on DeBeers' monopoly powers suggested
that they intimidated GE enough to not produce gem quality
diamonds.


Raghu,

GE currently is selling in volume industrial grade diamonds, However, they have developed and have sold gem grade stones but not in quantity due to lack of demand.

The Nova program dealt with some labs in Russia
that are producing virtually indistinguishable gem quality
diamonds. Infact, the only way that DeBeers could tell a
lab produced diamond was to look at the micro structure to
find the crystalline growth shape produced due to the way
seeding is done to grow the diamond crystal. That type of
analysis is not possible at the stores, so DeBeers is
considering putting their logo in the diamonds so buyers
can be assured that it is natural. A company in Florida
has bought the technology from one of the Russian labs
and will be selling the diamonds commercially soon.


A good gemologist can tell the difference under 30 power magnification.

A crystal of carbon, however differently it is formed,
is still a crystal of carbon, why all the fuss ;-))


No comment LOL <G>
