Frequently Asked Questions

What's the difference between lab-grown and natural diamonds?

Lab-grown diamonds are chemically, physically, and optically identical to mined natural diamonds — the only difference is where they're formed. Every lab-grown diamond we sell is IGI certified.

Is a 4ct lab-grown diamond more affordable than natural?

Yes — lab-grown diamonds typically cost significantly less than a natural diamond of the same size and quality, since natural diamond pricing reflects scarcity as well as the 4Cs.

What metals are available for 4ct engagement rings?

14K and 18K white, yellow, and rose gold, as well as platinum, handcrafted in-house in Miami's Diamond District.
