Banded agate, a natural, dark beauty! This one dates back to around 1860. It is simply set in a handmade 14k gold brooch. The setting is trimmed with a lovely rope design that adds a nicely textured contrast to the smooth, round, natural stone. The pinback is original and extra long, which was a standard of the time, and has helped us to date the piece. It measures 1 3/8 inches wide by 1 3/4 inches long, not including the pinback which adds an additional 3/8 inch. It is all in excellent condition, except a few minor scratches on the back of the stone.
