Crystal Toxicity - Be Informed - Be Aware - Be Safe!

Updated: Dec 9, 2019

Crystals, Gems, Minerals, Rocks, Stones, Aggregate, Fossils... whatever you call them, they are powerful elements from Mother Earth herself! In my Crystal Reiki Master/Teacher certification course I share with my students information about toxic crystals, their safe handling, safe uses and how to protect yourself when using toxic crystals. This blog today will be just a brief overview of the toxic crystals with which you should always use caution.

Crystals are used in healing, energy alignment, promoting abundance, for clearing, cleansing, protection and purification, and so much more! They have similar elemental properties as our own bodies; as well as similar vibrations as various components that make up our physical bodies (organs, bones, muscles, biological systems, neurites, neurons, etc.).

Crystals are used a lot in healing, due to their unique vibrations that match our own systems. Some crystals are programmable, and can be used to direct energies to a certain point/place.

Some people use crystals in water elixirs (be careful with that). While others put them under their pillow to reap their benefits as they sleep. Some wear them around their necks on their skin (be careful which crystals you choose to do this with) Others place crystals around and throughout their home to raise the positive vibration, clear and cleanse. Some put crystals in all four corners of their home for ongoing protection and purification. I have heard of people putting crystals under their floor boards and in their walls of their house to ensure protection and good vibrations. Crystals have a multitude of uses!

When considering working with crystals, it is not as easy as "pick a pretty rock and off you go". You will want to think about what are you using the crystals for? Will you be handling the crystals for a short time, a long time? What is the toxicity level of the crystal you are using? Using a crystal as a display or in a Reiki crystal grid is a completely different level of exposure than if you were to wear that crystals, or put it in an elixir and drink the water. NOTE: Under no circumstances should you ever use crystals on the "Cautionary Crystal List" in water elixirs, nor should you put them in your mouth for any reason.

Understanding which crystal properties are harmful, and which ones are not, will help you discern how best to handle the crystals. It will also help you in determining how best to use those crystals.

Crystals have different crystalline structures, and thus their toxicity levels vary with the different crystalline structures even if the toxin is the same as in other crystals. What I mean by that, is if you have a very porous crystal, there will be more points of exposure. If you have a very flaky crystal (like a shale or kyanite) the flakes that come off increase your exposure. If you have a rough natural crystal you will have a higher toxicity level than if you have a tumbled, polished, sealed one. If you have a crystal that erodes with use (desert rose, kyanite, sand stone, etc.) the natural wearing down process leaves the crystal residue behind, releasing toxins with every use. Some elements and metals increase in toxicity with use, such as mercury, releasing more and more mercury with every use.

Some crystals are artificially dyed or radiated, and can emit radioactive energies that could prove harmful. Some crystals emit gases that you need to be aware of such as radon.

Crystals are amazing and when handled correctly, and safely, they can provide an abundance of healing, protective and cleansing energies. So do not be afraid of using crystals, be aware - be knowledgeable - be informed!!

When in Doubt:

There are a lot of different web sites with lots of information on the toxicity of crystals. I would recommend that before you decide to use a crystal on your person google it for the most updated toxicity information on it (especially if it is touching your skin or you are using it in an elixir). Be informed!

I would also recommend, when you are purchasing crystals if you are not sure of their toxicity level, ALWAYS choose a crystal that has been tumbled and highly polished as any toxicity would be sealed and less likely to leach out during handling.

Radioactivity Concerns

Some forms of granite emit radon from the decay of Uranium. This is low risk.

Radioactive Gems. 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 – not Morion Quartz

  • Pink or red tourmaline

  • Deeply colored crystals

  • Colored Diamonds

  • Treated Kunzite

  • Cultured Pearls

Well there you have it! My ongoing list of crystals I recommend all my students to be cautious when handling. Do not be afraid of your crystals' toxicity, just learn how best to handle them.
