This is a lovely baroque Japanese akoya saltwater cultured pearl link bracelet. 

The pearls 6.00-7.50mm and are a round to semi-baroque shape. They have nice luster with rosy overtones. They are a blue/gray color and each pearl is a unique color.

It is set in yellow gold filled metal stamped "1/20 GF". From 1960's-1980's. Total length is 7 1/2 inch.

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