A 12x10mm rectangular cushion rainbow moonstone bracelet in rhodium over sterling silver measuring approximately 0.46 inch wide with box clasp and stainless steel tongue - the gemstone bracelet whose optical phenomenon is the entire reason for the piece. Rainbow moonstone exhibits adularescence: a billowing, floating blue-white glow that appears to move within the stone as the viewing angle changes. At 12x10mm, each stone is large enough to display its adularescence clearly. Box clasp with stainless steel tongue. For those who understand that the most compelling gemstones are often the most optically interesting.
