This is part of a family estate of vintage Asian artifacts. A silver toned nail guard not marked so could be Chinese silver. Channel set with Lapis,Jade,Coral,Carnelian and Pearl gem stones. The guard has been converted into a pin/brooch making a piece which is not only attractive but a conversation piece as well. The brooch measures 3 inches in length. Authenticity is guaranteed or full refund. I endeavor to keep my prices affordable but will consider offers.
