JJ (Jonette Jewelry Co.)

JJ is the mark collectors attribute to the Jonette Jewelry Company, an American costume jewelry maker known for figural and novelty pins.

JJ is the mark that collectors of costume jewelry attribute to the Jonette Jewelry Company, a Rhode Island maker known for figural and novelty pins: animals, holiday pieces and small characters.

We have not yet found a museum, archive or reference source for the company's history, and the collector accounts disagree on when it was founded and when it closed, so this page stays short until we can do better.

From our shop

The brooch we had in September 2026, from the 1980s, is signed JJ on the back. It is a small handbag in matte gold-tone metal that swings free from a bow.
