Lab Grown Rough Diamonds Description

Diamonds made in the laboratory cannot be distinguished from natural diamonds because they are diamonds. The only difference between them and natural diamonds lies in the place of origin. Although you can't tell the difference with an untrained naked eye, laboratory experts use technology to observe the subtle differences between crystal structures, which shows that crystals are developing much faster. Any trace elements found in diamonds can also tell experts where diamonds are formed, so whether they are man-made or natural.
Every time you buy an artificial diamond, you will get a gemstone certificate from the laboratory, proving that the diamond was bred in the laboratory. On the other hand, when you buy a diamond from the earth, you get a certificate from a rating agency describing its quality.
Although the diamonds produced in the laboratory and the diamonds mined by the earth are all diamonds, there are some obvious differences. First, the diamonds produced in the laboratory are ethical. Every diamond mined on earth has a past, and it's hard not to feel guilty when you're not sure where your diamond came from. After the birth of a diamond from the earth, it is almost impossible to trace its complete history, which shows that there is a lack of ethics in the diamond industry. Sadly, in countries where businesses are unregulated and criminal justice systems are lacking, diamond mines are full of horror stories of child labor and human rights violations. On the other hand, no one was harmed while growing diamonds in the laboratory.

Lab Grown Rough 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.
