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.

The rhinestones have gorgeous sparkle with no yellowish sets or damages. Unmarked as to maker.
