This is a nice strand of vintage Japanese saltwater akoya cultured pearls and yellow gold.

The pearls measure 6.00-6.50mm with great luster and bright rosy pink overtones.

The clasp is solid 14K yellow gold and has a modern basket weave style. It is stamped "14K". Total length is 17.50in, it is a choker. From the 1940's-1980's. 

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