The quick answer

The value of old costume jewelry depends on maker, era, design, stones, finish, completeness, and condition. Signed and well-made pieces can sell above ordinary fashion jewelry, but many mixed lots stay modest.

Value drivers

Signature: maker marks, hang tags, stamped backs, and original cards matter.
Design: figural brooches, rhinestones, enamel, parures, holiday forms, and runway-style pieces can stand out.
Condition: missing stones, dark foil backs, verdigris, broken clasps, worn plating, and glue repairs reduce value.
Completeness: matching earrings, necklace, bracelet, brooch, box, or card can help.

Photo checklist

Front, back, clasp, marks, stones, finish, and any original card or box.
