0.5ct DEF VS SI HPHT CVD Synthetic IGI Certified Lab Grown Diamonds
Certified Lab Grown Diamonds Description
The quality of diamonds is determined by 4C's. 4C's stand for cuts,
colors, carats and clarity. However, another important factor to
consider is the diamond certificate.
Through its certification, you can know a lot about diamonds. You
can tell if it's mined diamond or lab grown diamond. You can also
know whether the lab grown diamonds or nature diamonds have been
treated.
There is a reference to the details of diamonds to give buyers an
accurate idea of what they are buying. Although the information
seems simple on paper, different diamond laboratories provide
diamond information in different ways.
Each diamond will be analyzed in a laboratory with all the special
equipment and many tests. Measurements will be made and compared
with the main stone used for color grading in the laboratory. This
is how the quality grade of a diamond is obtained.
To make diamond certification credible, it should come from a third
party. The third party must be an independent company and not
participate in diamond trading in any way. Its main function is to
analyze diamonds and provide accurate images of diamond properties.
After analysis, the gemologist's findings will be listed on the
certificate.

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.
