The buckle was a popular 19th c motif used to indicate a close relationship. Gifts (rings, bracelets, etc.) w buckles were often given to a special person as a physical expression of an important tie binding the giver to the recipient. The age of this particular ring is unknown.
This pretty buckle style ring is set w many tiny Marcasite stones (white pyrite) which gives it extra sparkle. It is beautifully crafted, both on the inside of the ring & the outside. It is approx a size 7.
