Understanding Crystal Toxicity

Crystals to Handle with Caution


Crystals are composed of elements and minerals from the earth. Our bodies are also composed of elements and minerals from the earth. To ensure you do not overload your system with too many toxins, it is important to understand the toxicity of the different crystals you will be using.

Tumbled, polish crystals are much safer than raw exposed crystals because they are sealed with oils, reducing toxicity risk. Raw crystals are not sealed, and they have loose pieces and dust that may be toxic. If you are only handling a crystal for a short period of time (like creating a grid), that is much different than holding that stone for long periods of time (30 mins or more) during a meditation. The exposure length has a consideration in the toxicity concern.


Caution is recommended when choosing crystals to use in elixirs, where the crystals are placed in drinking water. There are many toxins that may leach out of the crystal when moistened. Some crystals are quite soft and can flake with use as well.

Due to the possibility of crystal toxicity, I would suggest using the type of water bottles that has a separate compartment on the bottom for crystals.

The main reason one would put crystals in water in the first place, is so the water absorbs the energy of the crystals. Crystals emit energy. They do not have to be in the water for the water to absorb the crystal’s energy. Water can absorb the crystal’s energy through matter and especially if you set an intention for that purpose. Just as moon water, which is water charged by moonlight, does not have to have the moon in it for the water to absorb the moon’s energy.

When working with crystals always remember to wash your hands off with cold water to wash away any toxins you may have picked up. Cold water keeps your pores closed, limiting the amount of toxins you will be exposed to as you wash your hands.

It is also good to note that some crystals are artificially radiated and can emit radioactive energy. Also, some forms of granite emit radon, so being mindful of how much time you spend around these types of crystals is important.

Radioactivity Concerns

Some forms of granite emit radon from the decay of Uranium. Radioactive gems or artificially irradiated crystals, gems or stones may be radioactive. Try to steer clear of the following:

·      Very deeply pigmented topaz

·      Artificially dark (almost black) Smokey quartz

·      Pink or red tourmaline and deeply colored crystals

·      Colored Diamonds

·      Treated Kunzite and Cultured Pearls
