1 Carat CVD Diamond F Color VS SI Clarity With IGI Certified Lab Diamonds
Certified Lab Diamonds Description
A diamond’s quality is determined by the 4C’s. These are the cut, color, carat, and clarity.
The 'Cut' of diamond is perhaps the most important aspect of
diamond quality that affects the beauty of diamonds. Diamond cut
refers in particular to the quality of diamond angle, proportion,
symmetry, brightness, fire, flicker and finish detail. These
factors directly affect the flash ability of diamond, as well as
its overall aesthetic appeal.
Diamond cut refers to the accuracy of its cutting and grinding
ratio and the perfection after finishing. Good cutting should
reflect the brightness and fire color of the diamond as much as
possible, and try to keep the weight of the original stone. The
cutting grade of IGI is divided into ID (Ideal), ex (excellent), VG
(very good) and G (good).
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 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.
