Lab-Grown Diamonds by KAY Collection
Lab-created diamonds are an exceptional mix of master craftsmanship and science - in fact, they have the same optical, chemical, and physical properties as natural diamonds. KAY Outlet lab-created diamonds are colorless, with little to no inclusions visible to the naked eye, for a stunning look that maximizes your budget.
