Marvella

Marvella is an iconic jewellery brand founded in Philadelphia in 1911 as Weinrich Bros. Co. The company later changed its name to "Marvella, Inc." and produced jewellery made of artificial pearls of excellent quality under the brand name "Marvella Pearls, Inc.". The company had many subsidiaries, and its hallmark changed frequently. The many changes in the hallmark are helpful to collectors as it simplifies the dating of ornaments, aided by posters produced by the company.
