15 Easy Steps To Identify And Sell Vintage Costume Jewelry
There’s a fine line between forgotten trinkets and collector’s gold, and it often comes down to a bit of know-how. Vintage costume jewelry has its own language, and once you learn to read it, you can spot and sell pieces like a seasoned dealer. Here’s how it’s done.
Look For Signs Of Age
Time leaves traces if you know how to read them. Focus on clasps and hinges for subtle signs of wear. True age shows up as soft fading or gentle loosening, and sometimes rust or grime. Once you know where to look, authentic wear leaves a clear and consistent signature.

Hunt For Maker’s Marks
Flip that piece over. Companies like Trifari, Coro, and Weiss usually stamped their names on the backs. Look out for symbols or full logos. Once you spot one, a quick search can date the piece and give a ballpark on value.

Study The Back Closely
The front might dazzle, but the back spills secrets. Older pieces may have open-back settings or older clasp styles like the “C” clasp. If it’s glued together or feels too smooth, it might be newer than it wants you to believe.

Plastics Can Be Surprisingly Valuable
Don’t skip the colorful beads. Bakelite, celluloid, and early Lucite are highly collectible. Tap them gently as Bakelite has a distinctive clunk, and a little rub-and-sniff test (smells like formaldehyde) can sometimes confirm the find.

Rhinestones Reveal A Lot
Glass rhinestones with foil backing, especially when hand-set, point to higher-quality vintage. If they’re dull or cloudy, don’t toss them just yet. Some gentle cleaning can bring life back, especially if the stones are original to the piece.

Color Palettes Offer Clues
Pastels and powder blues? You’re probably holding something from the ’50s. Deep jewel tones scream the ’80s, while neon plastic is pure ’90s chaos. When there’s no stamp to help you out, the palette might spill the decade.

Use Reference Books And Online Archives
Websites like Illusion Jewels or books by Judith Miller can be goldmines. They help you with ID-specific collections and match marks. Cross-reference everything before pricing; what feels rare might’ve been mass-produced, and what seems simple might be highly sought-after.

Clean Gently
Old rhinestones and fragile enamels don’t like water baths or aggressive scrubbing. Use a soft toothbrush and gentle soap, and avoid soaking. If you’re unsure, skip the cleaning and let a restorer handle it. One wrong move can ruin the resale value.
