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.
