Lab Grown Rough Diamonds Description
What's the difference between laboratory grown diamonds and diamond
simulants?
It is important to note the main differences between laboratory and
simulated diamonds. Diamond mimics, such as cubic zirconia and
carborundum, look similar to diamonds, but are not real carbon
crystals. The chemical and physical properties of simulated
diamonds are different from those of natural diamonds, so the price
of simulated diamonds is much lower than that of synthetic
diamonds. With the naked eye, the simulant can be distinguished
from natural diamonds or laboratory grown diamonds.
Natural and laboratory grown diamonds have thermal conductivity,
which can be distinguished from cubic zirconia by hand-held diamond
tester. Some laboratory diamonds, together with some natural
colored diamonds, may be mistaken for morsonite due to their
similar conductivity when using some diamond testers. However, due
to the different refractive properties of mosangite, gemologists
can usually distinguish between diamond and mosangite, where
mosangite is birefringent and diamond is single refractive.

Lab Grown Rough Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The Rough
Lab Grown Diamonds are produced in the laboratory, usually in a few
weeks. The chemical difference between the two is same.
So how do you distinguish between Rough Lab Grown Diamonds and
natural diamonds?
There is no obvious difference between the Rough Lab Grown Diamonds
and natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to discern subtle contrasts in diamond inclusions grown and
mined in the laboratory.
