This week we're going to talk about Inclusions in crystal, sometimes called Included quartz or Included crystals. This basically occurs when crystal is forming, and there are other substances present in the solution. These substances might be air bubbles or other minerals. They become trapped within the crystal during its growth. Air and moisture inclusions fall into the category of Fairy Frost, a non-mineral inclusion which we discussed a few weeks ago.
I have some pictures of Included quartz which I have adopted out through Arkansas Crystal Works, some of them from Arkansas, some from the Cascade Mountains in Washington. Crystal may be included with any number of minerals, some are more commonly found paired with quartz than others. The pictures I am going to share represent just a tiny percentage of the possible pairings. The inclusions may also appear in different forms, such as blobs, spots, specks, phantoms, whole minerals, needles, Rutile, etc. Here is a picture of Chlorite needles in quartz, (these crystals came from the Cascade Mountains in Washington State.)
