This is a lovely retro Japanese saltwater cultured akoya pearl and dark green nephrite jade double strand bracelet.

It features lustrous pearls with rosy overtones. They measure 4.50mm. The green jade tablets measure 7.50 x 10.00mm.

The pearls are wrapped on wire and the jade is bezel set. The clasp is stamped "1/20 12K GF" for gold filled. Total length 7 inches. From mid-century. 

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