After the verification, only PeerDiamonds and the buyer have access to the diamond.

Choose from the best

Above all other things, we take pride in the uncompromisable quality of each diamond offered on our marketplace.
To be eligible for sale, a loose diamond must meet the strictest quality criteria. Apart from having a GIA certificate, all diamonds must have a cut grading of 'Good' or above as attested by the GIA in order to be eligible for sale.
Also, each diamond must have GIA certified polish and symmetry ratings of 'Excellent' or 'Very Good'.
This emphasis on quality and the commitment to only allowing the best diamonds to be sold helps make PeerDiamonds the best place to buy diamonds and jewelry online.

What's more, for diamonds of the same specifications, the prices on the PeerDiamonds marketplace are on average 10% below those of any online diamond retailer and 40% below those of an average brick and mortar jeweler.
