This is a unique cameo necklace from the early 1900s. It has quite a bit of inticate wire workin and two large aquamarine stones that appear to be cut glass. The necklace measures about 17 inches from end to end and the shell cameo is about 1 1/4 inche from top to bottom. The metal is a white base metal that does not seem to be sterling it is made up in the jewelers shop so it is a combination of metals. A really nice piece of cameo history!
