ORA Jewelry (1930s-today).
ORA Jewelry was founded by designers Oreste Agnini and Ralph Singer. Initially, they produced buttons and brooches for Eisenberg.
The Chicago-based company employed 200 workers. Their early products were unmarked and only in the late 1930s, they began marking their jewelry with the brand name ORA. Motifs derive from nature, music and art-deco design.
The company is still in business but changed its name to Ralph Singer Jewelry.
