A December birthday is symbolised by a blue zircon birthstone. A beautiful and ancient stone, it signifies good luck, happiness, love and good health. People born under this stone are said to be free-spirited and born risk-takers. The Claddagh symbols in this sterling silver ring are also deeply meaningful, representing love (heart), friendship (hands) and loyalty (crown). This zircon Claddagh ring has been Irish hallmarked in Dublin Castle, and would make a stunning gift.
