This AAA-grade natural oval rainbow moonstone cabochon displays an intriguing luminous surface quality that is the result of the specific crystalline structure within the stone. The makeup of the stone creates a dramatic shift in the appearance of the stone as the wearer moves, making this an eye-catching choice for custom jewelry designs.
Rainbow moonstone is a variety of labradorite, a member of the feldspar group, and features an iridescent sheen called "labradorescence." This means that the stone displays colors that change depending on the angle and source of the light striking the stone surface. In rainbow moonstone, this characteristic is due to light reflecting from twinning planes within the stone. Ancient Romans believed moonstone to be rays of moonlight transformed into a solid form.
