Certified Lab-Grown Diamonds

Every piece in this collection has a certified lab-grown diamond, and the grading certificate comes with it. The certificate records the stone's carat weight, color and clarity as graded by a gemological lab, so you know what you're buying.

Most of these are stud earrings, from small everyday pairs to larger statement studs, with a smaller choice of rings, necklaces and pendants. Titles give the total carat weight, and many also give the grade, such as VS+ clarity and F+ color or VS/SI+ clarity and G+ color.

Lab-grown and certified

A lab-grown diamond is real diamond, grown in a lab rather than mined. A certificate doesn't change the stone, but it gives you an independent record of its grades, which helps when you compare pieces, insure one, or pass it on.
