Friendship, love and loyalty are represented by this historic celtic design. A Citrine claddagh ring with your birthstone or favorite color makes it even more significant. November's birthstone, citrine sparkles like honey. Carry the warmth and glow of a golden sunset with you by wearing a beautiful citrine ring. The birthstone of December, the tranquil azure color of a blue topaz ring can evoke thoughts of warm Caribbean seas on a cold winter day.
