Laboratory-Grown Rough HPHT Diamond Description

 

The laboratory-grown rough diamond are grown in the laboratory. They are composed of carbon atoms, have the same physical properties and chemical composition as natural diamonds, and have fewer impurities and higher purity than natural diamonds. And it's cheaper.

There are two techniques for growing diamond in the laboratory, one is the high temperature and high pressure method. This method is the most widely used. The other is chemical vapor deposition method. This method can obtain high-purity diamond without a catalyst.

What is the essential difference between natural diamonds and cultivated diamonds, mainly in the following points:

1. Formation time

Natural diamonds are formed under high temperature and high pressure due to geological reasons, and it takes tens of thousands or even tens of millions of years to produce. Cultivated diamonds are cultivated by scientists by simulating the growth environment of natural diamonds, under the same high temperature and high pressure conditions, through very sophisticated instruments, in about one to three weeks.

2. Crystal shape

Due to the different formation conditions, the properties of natural diamonds and cultivated diamonds are also different. The formation temperature of natural diamond crystals and laboratory-grown diamonds is almost the same, but natural diamonds will grow into octahedral crystals, while cultivated diamond crystals can grow into crystals that contain both octahedrons and cubes.

3. Color

The vast majority of synthetic diamonds are yellow, brown and yellow with hourglass bands; while natural diamonds are colorless, light yellow and other colors. At present, gem quality lab diamonds can also achieve colorless, which is almost unrecognizable to the naked eye.

Laboratory-Grown Rough HPHT Diamond 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.
