Five Ways to Spot Antique and Vintage Jewelry Worth Buying
1. Check the marks first. Karat stamps, hallmarks and maker's signatures confirm metal content, origin and often the era a piece was made. Look on clasps, earring backs and the inside of bands. Keep in mind that marks can be faked and plenty of genuine period work carries none at all, either because the stamp wore away or was never required. Treat a mark as confirmation, not as a pass-or-fail test.
2. Feel the weight. Solid gold and sterling are dense, and a real piece feels heavier than it looks. Something that seems featherlight for its size is usually thin plating over base metal. Hold two similar pieces at once and the difference is obvious.
3. Look at how it was built. Hand-set stones, tube hinges and C-clasps point to early, skilled work, generally before 1900. Screw-back earrings suggest roughly 1900 through the 1940s, since clip-backs took over in the 1930s. Glued components, rough seams and machine-perfect repetition point to mass production. These clues date a piece as well as grade it, which matters when the antique label depends on the 100-year line.
4. Examine the stones under magnification. Natural gems show tiny inclusions and slightly uneven hand-cut facets. Molded seams, swirl patterns and trapped air bubbles reveal glass. Unless a stone has been tested by a gemologist, treat any identification as unverified.
5. Never overlook the name. A signed designer piece can outsell unsigned gold. Costume work by makers such as Miriam Haskell or Eisenberg regularly brings more than comparable gold-filled chain, because scrap value and collector value are two different numbers. The signature is often what separates them.
