Antique 19th C Victorian Necklace Unique Etched 1880's

This is a lovely antique or very vintage necklace. I believe it is from around 1880. It has etched eastlake style square panels linked together. In wonderful condition but does need to be polished. It is about 17 inches long. I am not sure what type of metal it is. It almost has an art deco look. But I beleive it to be muh older. This comes from the estate of an antiques dealer and has been n storage for many, many years. I will be listed many unique Victorian and Edwardian jewelry peices from this estate, including mourning hair jewelry, military pins, bracelets, earrings, watch fobs and more. I will combine shipping. Buyer pays 3.00 shipping in U.S. 5.00 everyw else.
