This is a lovely graduated strand of vintage cream Japanese saltwater akoya cultured pearls and white gold.

The pearls measure 5.00-7.75mm with good luster and rosy pink overtones. 

The clasp is solid 10K white gold and is a filigree style. It is stamped "10K". Total length is 17 inch. From mid-century. 

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