Rough Lab Grown Diamonds Description

Laboratory diamonds, known as synthetic diamonds. At present, there are two methods of artificial cultivation of diamonds in the world: high temperature and high pressure method and meteorological precipitation method. These two kinds of diamond production methods are different, the products are the same, known as artificial cultivation diamond.

Both natural diamond and cultivated diamond are pure carbon crystals, and their physical, chemical, crystal structure and optical properties are exactly the same.Due to the different formation conditions, the nature of natural diamonds and cultivated diamonds are also different. However, natural diamonds grow into octahedral crystals (eight equilateral triangular facets), while cultivated diamonds can grow into both octahedral and cubic crystals (six square facets).

High temperature and high pressure synthetic diamond technology originated in the 1950s, initially mainly used in aviation and military industry, in the last decade has achieved a qualitative leap in technology, gem grade synthetic diamond in quality and cost has reached the level of marketization.

Rough 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.
