Irish Jewelry has long been steeped in cultural tradition and Celtic symbolism. It dates back to the ancient Celts. Brilliant metalwork examples have been discovered dating back to 2000 B.C and the 500 A.D. The rich tradition and symbolism of jewelry has made Irish Rings, Irish Pendants and Necklaces, Celtic knot jewelry, Celtic Cross, and Celtic wedding bands highly desired jewelry around the world.

Irish jewelers have been using Irish symbols like the Claddagh, Celtic Cross, Harp and shamrock and Celtic knots like the Trinity Knot, or Celtic Sisters Knot and Celtic Mothers Knot motifs in the Irish jewelry. These Irish symbols and Celtic designs are synonymous with the Irish jewelry.

It's the other way around: Irish is a Celtic language.
