About Primo Jewelry: Ring Sizer

What is my jewelry worth? Primo Jewelry is a jewelry identifier and jewelry appraisal app with a ring sizer built in. Snap one photo of a ring, necklace, bracelet, watch, antique brooch, costume jewelry piece or loose gemstone, and the AI tells you what it is and what it could sell for. JEWELRY VALUE FROM REAL SOLD PRICES Take a single photo and the AI identifies the piece (type, likely metal, stones and style), then estimates its value from real sold prices on online marketplaces, not asking prices or guesswork. You get an estimated resale value, a price range, and the comparable sold listings behind it. IDENTIFY JEWELRY, GEMS AND WATCHES - Rings, necklaces, bracelets, earrings, pendants and brooches - Loose gemstones, pearls and diamond jewelry - Watches, from the dial markings and style - Antique, vintage and costume jewelry - Hallmarks and stamps such as 14K, 925 or PT950, read from the photo when they are visible RING SIZER No printable strips and no guessing. Place a standard bank card next to your ring or finger, take two photos, and Primo Jewelry measures the inner diameter and gives your US ring size plus UK, EU and JIS equivalents, circumference and neighbouring sizes. KEY FEATURES - AI jewelry identifier and jewelry scanner - Jewelry appraisal based on comparable sold listings, not asking prices - Estimated price range and recent sold comparables - Camera ring sizer with US, UK, EU and JIS sizes - Local history of every scan and measurement - Choose your currency - No account required, your photos stay private WHO IT IS FOR - Owners asking what their jewelry is worth before selling or insuring - Resellers and thrift, estate and garage sale shoppers pricing their finds - Families valuing inherited, antique or vintage pieces - Anyone who needs a ring size fast, for an engagement or a gift Primo Jewelry gives estimates for guidance only. It is not a certified appraisal, an authenticity test or professional ring sizing. Always confirm with a jeweler when accuracy matters.
