Simple, seductive curvatures. Emblazoned in striking rubies. The Curvature was designed by Laykin et Cie in 1968. Originally created and still available in pave diamonds, this particular ring is defined by her uniform and unflinching commitment to the explosive color of 5 carats of gorgeous rubies, each tightly mounted in perfect uniformity. Available in sizes 5 - 9 in 18kt white or yellow gold.
