This Joseff of Hollywood crab, shell and 13 mm pearl brooch is in excellent condition. The mysteries of the Middle East influenced this design.
The detailed modeling is in the Russian gold finish they made famous for its photographic effect. The crab sits on a scallop shell and holds a large and lustrous simulated pearl. It is hallmarked Joseff signature on an applied plaque. It is 2" x 2 1/4".
Joseff was the jeweler for the Hollywood movie moguls form 1930-1948.
