This is a lovely pair of triple blue/gray Japanese akoya saltwater cultured pearl screwback earrings.

The pearls measure 6.50-7.00mm and are a blue/gray color. They have fantastic luster with rosy overtones. They are a baroque shape. 

They are set in solid sterling silver and stamped "STERLING" for sterling silver. Total length is 5/8 Inch. From 1930's-1980's.

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