Lab-grown diamond guide

A lab-grown diamond is a diamond grown by people, graded like a mined diamond, and priced lower.

Start with shape, cut, and grades

Start with shape and a carat window, then set a cut floor for rounds. Color G–H and clarity VS are a balanced target. Stretch to D–F or VVS only if the certificate grade is worth more to you than extra size.
