Should A Jeweler Show Me The Certificate?

“I was at a jeweler, and they said they don’t show certificates because it only confuses people. Shouldn’t they show me the cert so I know it’s for real?”

I can think of no reason for a dealer to hesitate showing you a Cert / Certificate from a nationally respected, independent gemological laboratory like GIA, AGS, or EGL…. UNLESS the diamond is not graded accurately. And that is still very common even in “fine” stores across the country. Most diamonds without certs are overgraded by at least one color or clarity grade… and perhaps both. This can mean you would spend as much as $1,000 extra for quality that is not there in a 1-carat diamond. Every tiny grade means a lot of money, even though a layperson could never see the difference.

This is why you should always insist on seeing a certificate from one of these labs before buying any diamond.
