Certified Man-Made Diamonds Description
Lab grown diamond’s quality is determined by the 4C’s. They are the cut, color, carat, and clarity.
Lab diamond color is graded in terms of how white or colorless a diamond is. The color of diamonds are graded from D to Z, with D being the most colorless, and Z containing noticeable brown or yellow tint.
The color of DEF is the first choice for many people when choosing lab grown diamonds. Indeed, colorless is completely white, which is really beautiful. Only in this way can everyone desire to have it. G ~ J color range is the choice of price and the actual needs of most people. Generally, it is not easy to distinguish the different colors if you are not a professional appraiser to watch the inlaid products with naked eyes. For example, although the colors of F and G are only one grade different, the price difference is relatively large, so it is a more objective method to evaluate the color of diamonds with a relaxed and rational attitude.
For consumers, a professional diamond certificate can clearly show the detailed characteristics of the diamond. So that people can clearly know the quality of the diamonds they buy.

Certified Man-Made 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.
