Certified Synthetic Diamonds Description
Whether it is natural diamond or lab grown diamond, the quality of
diamond is determined by 4C's.
What 4C's stands for?
4C's means Cut, Color, Clarity and Carat. The details as below:
Cut: quality of angles, proportions, faces and finishing details
Color: how colorless diamonds are
Clarity: how clean are the contents and blemishes of a diamond
Carat: the weight of a diamond
The four qualities of diamond are the key factors affecting its
beauty and structure. They determine the appearance and quality of
lab grown diamonds. For example, the ability of a lab diamond to
reflect light to the eye depends largely on the quality of the cut,
but also on the color and clarity.
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 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.
