This is a unique custom made blue/green chalcedony cameo necklace with saltwater cultured akoya pearl accents.

If features a cameo carved into a figure of a women in a bright blue/green chalcedony stone with white accents. The cameo is bezel set and measures 15x17mm. It is surrounded by 6.50mm white pearl accents with good luster, rosy pink overtones and light blemishes. 

It is in solid yellow gold with a spring ring clasp. Total length is 17 inch. Not stamped but solid gold. I was told this piece was custom made with an older cameo pendant and pearls. Pendant is early 1900's, pearls and chain are a little later, probably mid-century. 

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