Commonly effected are: Celestite, Fluorite, Malachite, and ChrysocollaĮstablishing mineral toxicity is complicated, and requires a good understanding of chemistry. Any mineral below the hardness of 5 is easily scratched by quartz. Commonly effected are: Gypsum, Halite, Pyrite, Optical CalciteĬonsult your Moh’s Hardness Scale. Commonly effected are: Amethyst, Fluorite, Rose Quartz, and some Calcitesĭo not immerse in water. Always remove turquoise rings before washing hands or doing washing up, and cleanse turquoise using a method other than running water. It will react adversely to oil, light, perspiration, cosmetics and household detergents. As it is difficult to know which rose quartz will be affected, it is probably best to keep all rose quartz out of the sun, unless for short periods when cleansing or preparing a crystal water or gem elixir. Some rose quartz is photosensitive, and will fade in colour if left in bright sunlight. We now know that this play of light is caused by microscopic spheres of the mineral crystobalite included in a silica gel within the gemstone, but the above corrections still work on a temporary basis. The dullness was temporarily remedied by saturating the gemstone with water, oil, or epoxy resin. It was long believed the play of light in precious opal was caused by included water, and that opals went dull when the water evaporated. If used in crystal waters or gem elixirs, it is unlikely to be poisonous, but the secondary method of preparation is strongly recommended, and if you ever happen to carve or drill it, do not inhale the dust particles. In addition, malachite is potentially toxic. It is also sensitive to heat, acid, ammonia and hot water. When carrying, it is best kept separate from other stones. Malachite is very soft (hardness 31/2 – 4), and therefore scratches easily and becomes dull in appearance. Sensitive to pressure – unlikely in crystal healing, but you never know. It can even disintegrate if left in damp conditions, such as in a cellar. Do not cleanse under running water, and clean either by dusting, brushing, or hoovering on the lowest setting. Halite is a salt crystal, and therefore extremely water-soluble. Although not toxic, use the secondary method when preparing a gem elixir or crystal water, in order to protect the crystal. Do not cleanse under running water, and clean either by dusting, hoovering on the lowest setting, or wiping with a slightly damp, very rung-out sponge or cloth. If left in for a period of time, they will eventually disintegrate. If immersed in water, crystals will initially go dull. They will absorb water and are water soluble, especially satin spar. Gypsum: Selenite, Satin Spar, Fishtale, etc.Īll gypsums are hydrous (containing water). Fluorite also has very strong cleavage planes, which will fracture easily when struck, so care when handling is recommended. It is photosensitive, and the colour will fade when left in sunlight. Calcite is also soft and easily scratched.įluorite is very soft (hardness 4), and therefore scratches easily and eventually becomes dull in appearance. Some varieties, particularly honey calcite, will fade when exposed to sunlight over a period of time. This can be immersed without harm, and is often used in crystal waters. Rough calcite will often have a smooth, waxy texture, indicating it has been resined. Therefore, amethyst should be kept out of the sun, unless for short periods when cleansing or preparing a crystal water or gem elixir.Ĭalcite can be affected by water, so it is best not to immerse it when cleaning or cleansing. Sensitive to exposure to acid – an unlikely occurrence in crystal healing, but worth taking note of.Īmethyst is photosensitive, and the colour will fade if left in bright sunlight. When creating a gem elixir, if in doubt, use the secondary method of preparation (see Gem Elixirs and Crystal Waters). Although the chance of poisoning yourself through handling of the crystals, or even using them to prepare a gem elixir or crystal water, is very slight, it is worthwhile to take note of them and to use particular care. There are also a number of crystals and minerals that are potentially toxic. Some crystals are water soluble, and should not be immersed in water or other liquids, others are soft and easily damaged, or affected by sunlight. It is good to be informed about these, so you don’t damage any of your precious tools, and also so they don’t damage you. For a variety of reasons, many crystals may need special treatment when in your care.
