A generic term for base metal alloys used in costume jewelry manufacture; while it is most often plated with gold or silver, during the 1930s many pieces were left un-plated as a cost-saving measure and collectors refer to these pieces as "pot metal" when describing them; pot metal usually has a dull finish similar to pewter when left un-plated.

This sparkling Art Deco fur/dress clip, circa 1930's, consists of large oval foil backed diamond rhinestones, prong mounted in an open-back pot metal mounting. In addition are pave mounted smaller round diamond rhinestones in connecting arched ribbons. The fur/dress clip measures 2 1/4" by 2 3/8" in size with study working metal clip mechanism. The rhinestones have gorgeous sparkle with no yellowish sets or damages. Unmarked as to maker.
