A Certificate is Akin to a Blueprint A trusted grading report is all your diamond needs to prove it is one of the best. Such a document can adequately detail the 4 C’s, as well as additional details including physical measurements, inclusions, fluorescence, etc. It also functions as proof of what you own, in case you ever need to leave your jewelry with someone and need to identify it later. It Benefits Insurance Purposes Jewelry insurance often uses grading reports as a way of objectively assessing quality. If you ever end up needing to make a claim, your grading report can serve as the foundation for it. It Helps When you Need to Sell It is romantic to believe you will own the same diamond for the rest of your life, but plenty of people sell theirs for money, which at the time they need more than jewelry. A grading report can help fetch a fair amount based on the characteristics of your stone.
