Who are we?

What Is a Lab-Grown Diamond?

A lab-grown diamond is a real diamond created in a laboratory using advanced technology that recreates the natural diamond-growing process. It has the same crystal structure, brilliance, durability, and chemical properties as a mined diamond. From custom engagement rings and fine estate jewelry to luxury timepieces and bespoke heirlooms, our specialists work with you one-on-one in our Newport Beach showroom.
