Primo Jewels: Ring Sizer & Gem

Primo Jewels turns your phone into a jewelry identifier, value estimator, and ring sizer. Snap one photo of any ring, necklace, bracelet, watch, or loose gemstone and let AI tell you what it is and what it is worth.

WHAT IS MY JEWELRY WORTH?

Take a single photo and the AI identifies the piece (type, metal, karat, and stones), then estimates its value using real sold prices from online marketplaces, not guesswork. You get an estimated resale value, a price range, and the comparable sales behind it.

RING SIZER

No printable strips and no guessing. Place a standard bank card next to your ring or finger, take two photos, and Primo Jewels measures the inner diameter and returns your US size plus UK, EU, and JIS equivalents, circumference, and neighbouring sizes.
