The feldspar family includes moonstone, sunstone, amazonite and labradorite.

  • Moonstone is an alkaline feldspar microincluded with albite crystals, which give it opalescent blue reflections.
  • Sunstone is a potassium feldspar and is also known as oligoclase. Known for its orange glitter due to haematite inclusions, it can also be found in gem quality in one deposit: Oregon in the USA.
  • Amazonite is a generally green alkaline feldspar with more or less turquoise inclusions of albite needles, giving it a silvery sheen.
  • Labradorite is a potassium feldspar. It is famous for its brown background and myriad reflections ranging from gold to midnight blue, green and violet.
