Design patent # 159,778 issued to Herman Bogoff in 1950
This 1950s brooch by Bogoff features a delicate flower set with multiple shapes of citrine-glass stones and a pavé stem. The setting is gold-plated base metal with a roll-over safety clasp. The dating of this piece is interesting, as the design patent was granted on August 22, 1950, yet the maker’s mark includes a copyright symbol, which typically wasn’t used on jewelry until 1955. This piece seems to be a 1950 design that was executed after 1955.
