This is a lovely pair of vintage textured grape Japanese akoya saltwater cultured pearl screwback earrings.

The pearls have very good luster and rosy pink overtones. They are between 4.50-4.75mm. 

They are not stamped but solid sterling. Roughly from 1940's-1970's. Hand detailed with brushed texture and stippling. Total length is 1 inch. 

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