3ct - 4ct HPHT Greentinch And Brown Color Lab-Created Colored Diamonds
Lab-Created Colored Diamonds Description
Laboratory grown diamonds are also called synthetic diamonds.
Laboratory diamonds are manufactured in the laboratory. CVD and
HPHT are two methods to make synthetic diamond.
What is CVD / HPHT laboratory grown diamond?
CVD is the abbreviation of chemical vapor deposition, HPHT is the
abbreviation of high pressure and high temperature. This means that
the material is deposited from the gas onto the substrate and
involves chemical reactions.
What's the difference between CVD and diamond mining?
The only difference between CVD diamond and diamond mining is the
place of origin.
Natural diamonds are natural products. It takes hundreds of
millions of years to grow underground, and CVD diamond is a
high-tech product that can grow in a few weeks. Because it's made
in the lab, it's of better quality. According to the same quality
standard, a complete and perfect natural diamond is very rare and
expensive.
What are environmentally friendly and conflict free laboratory
grown diamonds?
The diamond grown in the laboratory grows on the earth of the
diamond laboratory, which is different from the diamond mined;
There is no excavation and mining, so the integrity of nature and
natural resources is maintained. This helps the green environment.

Lab-Created Colored 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.
