Moonstone, the gemstone under the feldspar
What is moonstone?
Moonstone is an orthoclase with albite inclusions from the feldspar group that have formed thin layers during cooling. It is these layers that break the light and give the stone its typical shine. Pure moonstone is white, but can also be green, blue, red or even black due to a mix with other minerals.
Rainbow moonstone is a plagioclase feldspar and differs slightly from the normal moonstone which is an orthoclase (potassium feldspar). The difference is in the inclusions that provides the shine. In a rainbow moonstone it is caused just like the shine in a labradorite. The dark inclusions in some of these rainbow moonstones are black tourmaline.
In the time of the Romans, moonstone was a popular gemstone. It was believed that these stones were formed by the moon rays. This stone was often used in amulets and ornaments. Moonstone was also widely used in the Art Nouveau art movement.
