Friendship, love and loyalty are represented by this historic celtic design. A White Topaz claddagh ring with your birthstone or favorite color makes it even more significant. A sparkling white topaz ring is just the thing if you like diamond jewelry but you're on a budget. We won't tell if you won't!
