Friendship, love and loyalty are represented by this historic celtic design. A Garnet claddagh ring with your birthstone or favorite color makes it even more significant. One of the oldest gemstones in history, garnet is the birthstone of January. Garnet rings have been popular since Victorian times, and are treasured for their deep red color. Jade is the stone given in celebration of the 12th, 30th, and 35th anniversaries of marriage. For thousands of years, the stone has been revered in China and other countries throughout the world.
