What better gift than a sterling silver Claddagh ring set with the recipient’s own birthstone? People born in March are linked with aquamarine, and known for being honest, imaginative, trustworthy and excellent communicators. The aquamarine birthstone is said to promote knowledge and fight fear. The Claddagh’s symbols represent love (heart), friendship (hands) and loyalty (crown). This sterling silver ring has been Irish hallmarked in Dublin Castle.
