The Diavlia Diamond
A diamond you wear today.
Passed down tomorrow.
Our diamonds are grown, not mined, and certified by the same gemological institutes that grade the world’s most valuable stones. What you inherit is the grade, the hardness, the fire. What you leave behind is the mining.
10
Mohs hardness
Heirloom-grade
Mohs 10 hardness, the hardest natural material. Graded by IGI on the same scale GIA uses for mined diamonds. Passed down the same way, 40 years from now.
100%
IGI certified + inscribed
Traceable from seed
Every stone grown in a facility we audit. The laser inscription on the girdle links your specific diamond to its IGI paper report. Provenance without ambiguity, ever.

Before you buy
Six questions,
honestly answered.
No sales-floor hedging. These are the exact answers we’d give across a counter.
Are lab-grown diamonds real diamonds?+
Yes. A lab-grown diamond is chemically, physically, and optically identical to a mined diamond: pure crystallized carbon, Mohs 10 hardness, the same refractive index and dispersion. The only difference is origin. IGI grades them on the same 4C scale used for mined stones. The FTC formally classifies them as diamonds.
Read the full comparison →What does my IGI certificate actually verify?+
Every Diavlia diamond ships with an original IGI paper report that independently verifies carat weight, color grade, clarity grade, cut grade, polish, symmetry, fluorescence, and the laser-inscribed serial number on the girdle. You can re-verify the report yourself at igi.org/reports using the certificate number, before or after purchase.
Inside the 4 C’s →What happens if I don’t love it when it arrives?+
Return it within 14 days for a full refund, no restocking fee. We include a prepaid, fully insured return label in every package. The item must arrive unworn with the original certificate and packaging. Engraved pieces are the only exception.
Full shipping & returns →How does the Lifetime Upgrade Program work?+
Trade your center stone toward a larger one at any time in the future. Your original purchase price is credited in full, no depreciation, no time limit, no pre-declared anniversary. You pay only the difference. Every engagement ring is auto-enrolled the day it arrives.
How the upgrade works →How long will my order take to arrive?+
Every piece in our collection is in stock and ships within 1–2 business days, arriving 2–5 business days later across the US, insured and signature-required. You’ll see the exact ship date on every product page and a tracking link in your confirmation email.
Shipping & returns →How do your prices compare to Brilliant Earth, Blue Nile, Vrai?+
For equivalent IGI-certified lab-grown specifications, Diavlia is priced 20–35% below the major competitors. A 1ct VS1-F excellent-cut round is approximately $1,900 with us versus $2,650 at Brilliant Earth. Our pricing reflects no showroom overhead and a lab-grown-only catalog.
