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

The pearls have very good luster and rosy pink overtones. They are between 4.50-5.50mm. 

They are stamped "STERLING 950" for slightly more pure than sterling sterling. Roughly from 1950's-1980's. High polished texture with swirling leaves. Total length is 3/4 inch. 

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