Ceol mo Chridhe (R) Music of my Heart Also available in 14K Yellow, Rose and White, as well as 18K Yellow, and Platinum. Hearts are traditional in late medieval Scottish and Irish decorative art. About 1990 Walker and a number of other Celtic designers spontaneously and independently incorporated the heart into the knotwork tradition of Celtic art. The popularity of the Claddah ring (heart, crown and hands) has made this design equally popular with men and women. Approximately 9mm wide at front tappering to 5.5mm at back.
