What? Diamond warranty? ***** in your diamond because it wasnt cleaned or inspected? Do they charge you for these cleanings and inspections? This sounds like an out and out scam to me. Places dont guarantee their diamonds, there is no reason to. Diamonds dont just ***** because they dont get cleaned. Diamonds are the hardest substance on earth, the only thing that would make one ***** is that a great weight is placed on it, or its struck really hard- nothing to be guaranteed against there, if you drive your car over your diamond and ***** it, thats your loss. I personally would go to another jeweler to find out if its even is real diamond, to be honest with you. And most places will give you a cleaning for free (even if you didnt buy the ring there), and the only “inspection” that might ever be needed would be to look at the mount, to make sure the diamond isnt loose. The only guarantee that most places offer on their diamonds are that they are accurately described in the appraisal, that they are genuine, and thats about it. They arent tv’s or washing machines after all.

Diamond cracks can’t be repaired if it is a true diamond!

Every time you buy a diamond it must have a GIA certificate, otherwise it is not a true diamond.
