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

The pearls are graduated and measure 3.50-7.25mm with good luster and rosy overtones. They are a white color. Some natural blemishes and the pearls near the clasp are a little less lustrous due to wear. 

The clasp is solid 14K yellow and has a modern style. It is stamped "14K". Total length is 20.50in. 

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