CVD Lab-Grown DiamondsEvery stone in this collection is lab-grown by CVD — physically and chemically identical to a mined diamond, because it is one.
D-E-F Color · VVS1 ClarityWe hold the whole line to near-colorless D-E-F color and VVS1 clarity. No cloudy, yellow-tinted stones.
IGI Certified Ring CentersThe center stone of every lab-grown diamond ring comes with IGI certification.

Lab-grown diamonds test as diamonds, sparkle like diamonds, and last forever like diamonds — the difference is the origin and the price tag. Instead of paying for mining, you pay for carat weight, cut and quality. Read our lab vs. natural guide — and note we also carry a full line of natural diamond jewelry if mined is your preference.

Lab-grown diamond FAQs

Are lab-grown diamonds real diamonds?
Yes. They are diamonds — same carbon crystal, same hardness (10 on the Mohs scale), same sparkle. A jeweler's diamond tester cannot tell them apart from mined stones; only specialized lab equipment can.

What does CVD mean?
CVD (Chemical Vapor Deposition) is the growing method: a diamond seed grows layer by layer in a controlled chamber. Our entire lab-grown line is CVD-grown.

Why are they less expensive than mined diamonds?
No mining, shorter supply chain. The savings go to you — which is why a bigger, higher-quality stone fits the same budget.

Can I see the full collection?
Yes — browse the complete Diamond Collection, or message us on WhatsApp at +1 (732) 290-5335 and we'll help you pick a piece.
