This is a stunning pair of cluster style Japanese akoya saltwater cultured pearl screwback earrings.

The pearls are white and round with great luster and rosy pink overtones. They measure between 4.75-6.25mm. 

They are stamped "STERLING" for sterling silver. They have a climber style with one pearl higher up than the others. Total length is 3/4 inch. From mid-century Japan.

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