Embrace your Irish heritage. Our Created Opal sterling silver ring is a sensational way to showcase the symbol of the triquetra and sparkle with the iridescence of Created Opal jewelry. The symbol of the triquetra is believed to represent three promises of a relationship, which are to love, to honor and to protect. The oval Created Opal stone on our Celtic knot ring emits a rainbow of colors, depending on the way the light reflects on the stone. The colors seem to change from hues of pink and purple to yellow, green and orange as you move, giving our Celtic ring a remarkable rainbow effect. Consider purchasing this piece of October birthstone jewelry for a close friend who celebrates an October birthday or as a great choice for St. Patrick's Day gifts for loved ones.
