Synthetic Diamonds
The first synthetic diamonds were produced
by General Electric in 1954. A synthetic
diamond is basically a rock that has the
durability, refractive index and hardness of
a natural diamond – but it is made by man.
A synthetic diamond should not be
confused with stimulant diamonds, such as
glass, cubic zirconia, or moissanite.
Although the technology for synthetic
diamonds came into play in 1954, no
synthetic diamonds were ever seen on the
market until the 1990’s. This was due to the
fact that it took many years for General
Electric to produce a synthetic diamond that
could compare with the quality of a natural
diamond – and when they figured out how to
do it, they found that it cost more to produce
a synthetic diamond than it did to mine and
cut natural diamonds.
Finally, a small company by the name of
Gemesis Corporation figured out a way to
produce synthetic diamonds that were of the
same quality as natural diamonds, at a
cheaper price. Today, Gemesis produces
synthetic white diamonds, and colored
diamonds as well. These diamonds sell for
about 1/3 of the cost of a natural diamond,
but there is a shortage of them, and they are
hard to find. In fact, it seems that synthetic
diamonds are rarer than natural diamonds!

How Diamonds Are Cut
In their most natural form, diamonds are –
well – quite ugly. They have no luster or shine,
and in fact, look like nothing more than
broken glass. A diamond must be cut, and
then polished before it actually becomes a
thing of beauty.
Diamonds are cut with saws, into round
shapes. From the rounded shape, other
shapes may be cut, such as heart shapes
– but the shape is less important than the
quality of the cutting that is being done. If
the diamond is poorly cut, it will lose light,
and it will not sparkle and shine very well.
Each facet of the diamond must be
carefully cut into the geometrical shapes
that allow the diamond to sparkle and
shine, then the entire diamond is cut into
a specific shape, such as an emerald cut
or a princess cut diamond.
Once the cut is done, the diamond is put into
a dop, which resembles a cup with another
diamond – only a diamond is strong enough
to smooth the edges of another diamond.
Once the diamond has been cut and shaped,
and had the edges smoothed in the dop, it is
polished on a scaif or a diamond polishing
wheel.
