S-curvesThis ring is a variation on the Classic Round Tension ring, but has a sculpted area that grips on the stone. The stone is held firmly between arms that wrap around to contact the stone at an angle. This is a very classy ring. A round diamond or an optional Cubic Zirconia or other gemstone can be used. Each ring is individually designed for the exact dimensions of your stone. Because the ring profile is symmetrical, it is recommended for smaller stones
