Vintage Flower Brooch, Sterling Silver, Green Calcite Cabochon Stone, Signed Me

This exquisite sterling silver flower brooch has a domed Calcite cabochon stone in the center surrounded by a twisted metal "rope" detail and dimpled petals all the way around. Circa mid 20th century. It is signed Mexico Silver on the back. Clasps with a C-clasp. Unpolished with wonderful vintage patina. Very pretty and unusual vintage statement piece!
