Guides
A natural diamond is a mined diamond. The certificate is how you know the one you pay for is the one you receive.
GIA is the report many buyers ask for by name. IGI and other labs on the site also grade natural stones. Compare like with like: same shape, similar carat, then color and clarity.


Because natural prices climb quickly with size, be honest about the budget first. A bright 1 carat natural round with an Excellent cut will outperform a larger stone with a dull cut.
