The Criteria for IGI Diamond

IGI grades lab grown diamonds known as 4 Cs: carat, color, clarity, and cut.

Carat:

All the diamonds are measured in carat, which is directly related to their weight. Generally, larger diamonds have more weight. There is no control overweight for natural diamonds, whereas, on factory made diamonds, manufacturers have some influence.

Color:

Pure diamonds are colorless, which means transparent. Many diamonds have impurities, such as hydrogen, boron, etc. Hence, grades for colors are characterized from D to Z. ‘Z’ being light-colored and ‘D’ being colorless.

Clarity:

It has a scale that runs from I to FL. ‘I’ being included means the diamond has flaws, and ‘FL’ being flawless means the diamond does not have any flaws.

Cut:

The cut is the essential grade for a diamond, representing how much light will reflect from the diamond. As a result, it means the quality of the diamond.
