This is a gorgeous red enamel rose brooch set in silver metal, with pave white stones on the leaves and center, red pave stones on the petals and white bagette stones on the stem.  It measures 1-3/4 inches high, and could be worn with a chain as a necklace, and if you got a pin to necklace converter, it could be worn horizontally as a necklace.  It is beautiful!
