This lovely engagement ring easily fits a half carat diamond. The design was inspired by an experience on a canoe at night, the clouds parting to allow moonlight to reveal the swirls from my paddle on the lakes surface. Being in a psyche-celtic frame of mind, thus arose the celtic swirl ring. Its available in a wide or narrow version. A matching band is available in the same width as celtic medium band (#3 turns into #22 with a notch) or celtic thin (#4 turns into 22a, with a notch to accommodate the engagement ring).
