Gypsum
Gypsum is a form of calcium sulphate which comes in a variety of forms. It is most commonly found in the form selenite which is formed of long slender needle like crystals that form compacted together, almost like fibre optic cables. Another rarer form can be found as large clear crystals that are often found inside geodes of amethyst, quartz or calcite. These crystals exhibit a monoclinic structure and have a hardness of 2.
Gypsum, when found in the two varieties mentioned above, is extremely uplifting and positive. This stone is often called the bringer of light and will bring light to any dark corner of a room or a mind.
This is a great crystal to have in a healing collection
