Certified Lab Grown Diamonds Description

Diamonds are made of pure carbon in the shape of a tetrahedron. Diamonds are famous all over the world as luxury and precious jewelry. However, it is also the hardest substance in nature, a good heat conductor and an inert substance.
HPHT is the primary method used to grow rough diamonds in a laboratory. At present, the world's popular high-temperature and high-pressure synthetic diamond equipment mainly includes two side top, six side top and bar split sphere or improved split sphere.
CVD stands for chemical vapor deposition, which is one of main methods to make lab grown diamonds. The growth of this kind of diamond requires proper pressure and temperature of the hydrocarbon gas mixture in the vacuum chamber.

CVD diamond growth process
Place the diamond seed in the diamond growth chamber.

A carbon-containing gas is injected into the growth chamber.

Heat the growth chamber to 900-1200°C.

The microwave beam causes carbon to fall from the plasma cloud and deposit on the seed crystal.

Every few days, the diamond is taken out, the top surface of the diamond is polished, and the non-diamond carbon elements are removed from it, and then returned to the growth chamber. Each batch of diamonds may need to go through several start/stop cycles, and the entire growth process takes three to four weeks.

For consumers, a professional diamond certificate can clearly show the detailed characteristics of the diamond. So that people can clearly know the quality of the diamonds they buy.

Certified Lab Grown Diamonds Introduction

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the 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.
