About Moonstone
Moonstone is a member of the Feldspar Group of minerals that also includes Albite, Amazonite, Andesine, Anorthite, Bytownite, Hyalophane, Labradorite, Moonstone, Oligoclase, Orthoclase, Sanidine and Sunstone. Moonstone is a popular name for Orthoclase and/or Plagioclase Feldspar showing a blue sheen. The blue sheen is produced by the presence of very finely dispersed Albite crystals or plates within a body of Orthoclase or Labradorite. This blue sheen is referred to as adularescence. Blue Sheen Moonstone with a colourless and transparent body free of inclusions makes for a rare and beautiful gem. Common Moonstone is usually translucent to opaque or heavily included.
Moonstone gets its name from its bluish glow due to adularescence. The name Orthoclase is from the Greek words orthos meaning right and Kalo meaning I cleave because its cleavages are at right angles. Feldspar is the Swedish Feldt + spat meaning that it was found in fields overlying granite.
