When we buy diamond jewelry, the diamond grading report is essential, which is the certificate we often say. A reliable report can help you gain a deeper understanding of the diamonds set in your jewelry. Grading reports from trusted laboratories can also act as a safety barrier against the purchase of processed and synthetic diamonds.
Gemologists perform a series of tests and scientific analyses on diamonds to detect artificially processed color and clarity. It provides us with scientific evidence that diamonds are properties and characteristics, and also proof that they are natural diamonds.
There are countless gemological laboratories around the world, but not all laboratories issue the same certificate. Each gem lab will use its own scoring system and terminology. इसलिए, reports from two gemological laboratories on the same diamond may have different results.
