This is a lovely vintage graduated Japanese cultured saltwater akoya pearl and yellow gold necklace.

The pearls measure 4.00-7.25mm with great luster and bright light overtones. They are a white color and graduated. Very light natural blemishes. 

The clasp is solid 14K yellow gold and has a floral filigree style. It is stamped "14KT". Total length is 16.75in. From the 1950's-1980's. 

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