Moonstone

More about this category

Moonstone is a feldspar, a variety of orthoclase. Its milky, shifting sheen, known as adularescence, comes from fine alternating layers of feldspar that scatter the light.

  • Colour: white, cream, grey or peach, with a bluish sheen.
  • Family and hardness: feldspar (orthoclase); Mohs hardness 6 to 6.5.
  • Traditional symbolism: With its pearly sheen reminiscent of the moon, it is traditionally associated with intuition, cycles and gentleness.
  • Care: Quick rinse in lukewarm water, then dry. It cleaves easily: protect it from knocks and heat.

The “rainbow” moonstone commonly seen in shops is generally a white labradorite, from the same feldspar group; classic moonstone (adularia) shows a softer bluish sheen.
