This is a lovely set of mid-century Japanese akoya saltwater cultured pearl screw back earrings and pendant set.

The pearls are 4.50-5.75mm round. They have good luster with rosy overtones. They are surrounded by silver cadges with the pearls free floating. They are stamped  "STERLING" for sterling silver. Earrings measure 1 1/4 inch long, pendant is 1 inch. 

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