This is a stunning vintage Japanese saltwater akoya cultured pearl ring by Fuji Pearl. Fuji Pearl was a high quality designer that went out of business around the mid-century.

It is set in solid white gold. It is stamped "WGK14" and "FP" for Fuji Pearl. US size 3 1/2, for a very small person or a pinkie ring. 

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