How We Verify Every Ring

Every ring on Vow is authenticated by a certified gemologist before it ships — no exceptions.

Solitaires & unbranded rings

These come with a physical GIA (Gemological Institute of America) certificate, the diamond industry's gold standard. Each stone is graded on cut, color, clarity, and carat weight by GIA's laboratory in Carlsbad, California. The certificate ships with the ring.

Designer rings (Tiffany & Co., Cartier, David Yurman, Harry Winston, Verragio, Bulgari, Van Cleef & Arpels, and others)

Every designer ring is inspected by GIA experts through eBay's Authenticity Guarantee program. GIA-trained gemologists physically verify the piece — including hallmarks, metal composition, and stone authenticity — before it's cleared to ship.

What this means for you

You never buy a ring that hasn't been examined by a professional. If a ring can't be verified, it doesn't leave the seller.

Combined with our 30-day money-back guarantee

If anything about your ring isn't as described when it arrives, you have 30 days to return it for a full refund. See our Refund Policy for details.
