Celtic designs are wonderful, and the swirl patterns are perhaps the very best of the lot, being both ornate and elaborate, but still elegantly simple and pleasing to the eye. We make the center sections approximately 1.4-1.5mm in thickness, and suggest bordering the center pattern with a framing rail. We offer these in many different styles as well, in the more flatsided, slightly elevated style you see here, and with standard half rounds for the sides, in all metals and colors. Single Colors are great too, there's an 18Kt version you should see :)
Note that the diamond is shown set in a bezel, to honor the ancient theme, but the center can be elevated in a basket crown, standard solitare peg top or customized to your tastes for your diamond, or ours. Crowns and Tops are described on their own page now. Also, for colored stones and personalized these can't be beat! Too see more poke around the main custom page, many wonderful things are linked there :)
