Colored Lab Grown Rough Diamonds Description
Laboratory grown diamonds are not mined from the earth. Laboratory
grown diamonds are not fakes, not cubic zircons, not crystals. They
have the same chemical composition as natural diamonds. Laboratory
diamonds are made in the laboratory. It starts with a small
chemical called diamond seed. Then it's exposed to high
temperatures, plus a layer of carbon coating, all of which are
designed to help laboratory made diamonds crystallize as they grow.
Diamonds grown in the laboratory have the same optical and chemical
composition as diamonds produced on earth.
Although scientists have been using this method since Mid-1900, the
diamonds originally made are pumpkin colored. Only in recent years
have scientists found a way to make white diamonds. There are two
main ways to make laboratory grown diamonds. One is to use
ultra-high pressure and high temperature to simulate the natural
diamond growth environment and dissolve carbon into diamond seeds;
Another method is to put the diamond seeds into a special diamond
microwave oven, inject carbon gas into the microwave oven and stick
it on the seeds to slow down the growth of the seeds.

Colored 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.
