Are Diamond Certificates Crucial?

Exclusive articles on How to Read a Certificate, are the only resource for this information that we have found anywhere. They explain every detail on a certificate and how it affects the beauty and price of a diamond — in simple terms
Why certificates are crucial:
Get What You Pay For
Diamonds are priced by their actual quality grade, according to the 4 Cs
Unless you receive a diamond grading report (almost always called a “certificate”) from a respected laboratory that has no financial interest in the diamond you are buying, you are certainly not getting the exact quality you wanted to buy.
Small, local labs are often connected in some way with a store, so they tend to grade diamonds more favorably in order to help make the sale. The GIA and EGL labs are very conservative in their grading because they do not sell diamonds and do not receive any portion of diamond sales. A certificate from one of these labs is the best way to get the diamond you want and avoid paying an F color price for a G color quality.
Security During Repairs
People sometimes ask: “How can I be sure I will get the same diamond back when I have it cleaned or repaired at a jewelry store?” Though it is actually very rare that any jeweler would switch stones intentionally, accidents can sometimes happen in a busy store or factory. The key is to have a certificate that maps your diamond’s unique inclusions like a fingerprint that you can check before you accept it back.
