This is a lovely botanical pair maple leaf Japanese akoya saltwater cultured pearl screwback earrings.

The pearls are lustrous with pink overtones. They are small and measure 3.50mm each. They are stamped "STERLING" and "HSB" for a Harry S. Bick. A well known designer out of NYC in the 1950's. Detailed leaves and nice craftsmanship. Total length is 1 inch. 

All pearls are truly vintage and have only been lightly cleaned.
