Below are additional design cards and jewelry photos accompanying the article Eisenberg & Ralph Singer Jewelry: A Tale of Two Companies. Most of the jewelry made for Eisenberg by Ralph Singer Co. was not marked so these design cards may help you identify unsigned pieces made from the mid-1920s through the 1930s.
Also noted at the bottom of this feature is an example of Anne Geyer’s work for Ralph Singer & Co. under the ORA brand beginning in 1954. Geyer, who formerly designed for Tiffany & Co., drew her sketches on black paper rather than index cards.
