Lab Grown Rough Diamonds Description

 

At first glance, you may believe that the diamonds made in the laboratory are simulated diamonds. In fact, they are 100% real because they are chemically and structurally identical to the diamonds mined by the earth. In fact, any jeweler can use the technology they have, and it will tell them that the diamonds produced in the laboratory are real.

Diamond mimics are "synthetic diamonds" that look like them, but can offer a lower price point. Some of the main diamond mimics include cubic zirconia and carborundum. Although they all have a clear crystal appearance, the properties of diamond mimics are very different from diamonds. Unlike diamonds, these crystals are not carbon based, and you don't need any equipment to see the difference. Because colored diamonds are very rare in nature, it is easy to mistake laboratory grown colored diamonds for cubic zirconia or morsonite.

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.
