The beautiful rubellite stone is a variety of tourmaline. Hailing from the Ouro Fino mine of Brazil, Ouro Fino is one of the world's first premium rubellites. This particular ring is made in platinum over solid sterling silver. The platinum plating makes the jewelry more durable and adds a decorative appeal to the piece, while helping to enhance the metal-life. The seven rubellite gemstones are channel set so you will never lose a stone. The color is a vibrant pink-purple-red. This ring is a size 9, and is stamped 925 and signed. An added plus is the platinum plating will prevent tarnish! It is gorgeous!
