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.
