This is one of the nicest Scottish brooches I have seen in a while. I love the pinkish agate, and the petal shape of this piece. It is a brooch, with it's original "c' clasp, and "t" hinge, but it also has a ring, so it could be suspended from a chain, and worn as a pendant. It is circa 1870, and in excellent condition. It measures about two inches in diameter. This one is really nice.
