End of the Victorian -early Edwardian ornate silver guild over brass with larger cut jet glass bead accent. I think this is French jet glass. The sort of organic nouveau nature theme lends itself to the Edwardian date. However it also has a heavier gothic feel. So, it could be slightly older or 1880s-90s. The chain seems to be hand done hammered links. See images of the clasp. It is truly gorgeous! I love the one bigger jet bead hanging from the elongated hollow pendant. This is from the same estate/owner of many of the other 1920s pieces. Many of these came over with her from Europe. The jet glass was common in mourning jewelry. Condition is Excellent with only minor finish rub to silver gilt on front showing fine brass exposure. See images.
