WOW! This is a gorgeous, LARGE necklace. The metal is sterling silver, but is not marked, and has a wonderful lustrous patina. The amethyst and quartz colored stones are probably charoite. Charoite is a quartz-like mineral discovered near the River Chara in Eastern Siberia in 1978.
The eight stones are all hand set and the setting is hand chased. The necklace design is similar to the squash blossom necklaces of the American Southwest.
The necklace is 22 inches long, with about a 14-inch drop including the pendant. The typical stone is about 1 inch by 1/2 inch in size. Excellent condition.
