Rainbow Moonstone Round Cabochon

This rainbow moonstone cabochon displays an intriguing luminous surface quality that is the result of the specific crystalline structure within the gemstone. The makeup of the gem creates a dramatic shift in the appearance of the gemstone 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 gemstone displays colors that change depending on the angle and source of the light striking the gemstone surface. In rainbow moonstone, this characteristic is due to light reflecting from twinning planes within the gem. Ancient Romans believed moonstone to be rays of moonlight transformed into a solid form.
