Guides
Two diamonds with the same carat can have very different prices. The report tells you why.
The big drivers are origin (lab-grown or natural), carat, and the 4Cs. Shape is next: rounds command a premium. Certificate lab matters to some buyers; GIA and IGI are the reports you will see most often here.

Fluorescence, measurements, and whether a photo exists also change what people will pay. A cheap stone with no image is not comparable to a photographed stone at a higher price.

Carat Mate shows the price of a specific certified diamond, not a generic “1 carat from $X” package. When you buy, that is the stone that ships with its lab report.
