Safety Disclaimer

Mountain Aura does not encourage using crystals for items such as (but not limited to) drinking from, smoking from, or consuming but suggests that if you do feel this is what you are wanting to do, to do your own research prior to using any crystal for these types of actions. Mountain Aura will not be held responsible for your actions and health results of your actions once your naturally formed crystal is in your possession. Mountain Aura does not test its products for composition, nor do its vendors, and rely on average crystal classification for composition only.

Crystals are a natural product, removed from the ground. As such, in raw form it is possible they can contain trace amounts of natural hazardous materials such as but not limited to the potential to contain Asbestos. When crystals have been processed and then handled properly, there are less chances that you will come into contact with potential hazardous materials. Crystals with the potential to contain Asbestos or contain minerals formed from asbestos could be:

Tiger’s eye
Arizona tiger’s eye
California tiger’s eye
Cat’s eye
Hawk’s eye
Silkstone
Pietersite
Binghamite
Yuksporite
Denisovite
Tokkoite
Grossular garnet
Hessonite
Brucite
Natrolite
Mesolite
Scolecite
Tremolite
Actinolite
Crocidolite

To have a harmful exposure to asbestos from processed crystals is difficult, as any potential asbestos is generally contained. The asbestos would have to be released in some manner, by processing, grinding, creating powder etc, and then ingesting or inhaling that substance. A higher degree of care and caution should be taken with raw minerals as dust and debris can easily come loose while handling and be accidentally ingested or inhaled. Ensure proper handling is always achieved, or specimens are contained.

Proper handling means not ingesting these substances under any circumstances, do not smoke from these materials, do not submerge in drinking or bathing water and do not use products that have come into contact with these products such as bath salts and drinking water. With raw crystals, limit your handling time and always wash your hands after handling. Extra caution should be taken when processing raw product such as using gloves, protective eye wear, respirator and other appropriate PPE materials. There is debate on how products such as Tigers eye is formed, some say that the asbestos is replaced with Quartz during the formation process, but others say that the Quartz is formed parallel to the asbestos, so to maintain proper health, always use caution.

Gemstone Toxicity During Normal Handling

Most minerals are safe to handle normally. However, radioactivity in minerals containing uranium and thorium should be assessed using a Geiger counter prior to handling. Water soluble gems will also require extra care.

While certain heavy metals have adverse effects at any concentration, others are far less toxic.

Gemstone Toxicity While Cutting

Lapidaries should exercise caution when cutting potentially toxic minerals. Inhalation or accidental ingestion of particles could be detrimental to your health. Furthermore, inhalation of asbestos and silica can be physically toxic.

For additional information, see our articles on lapidary health hazards and safety tips and toxic and radioactive gem safety tips.

Potential Toxicity for Intentional Gemstone Ingestion

Crystal healers should avoid making potions with toxic gems. They should also avoid putting these gems in their or their patients’ mouths. In addition, some gems have no known toxicity but are still soluble in acids. If you swallow particles of these gems, their dissolution in your stomach could release impurities in the mineral. Certain gems may react dangerously with stomach acid to produce hydrofluoric acid (HF) or hydrogen sulfide gas (H₂S). Avoid ingesting gems that may produce these dangerous substances.

Finally, most lists of toxic gems on crystal healing websites include aluminum and a few other elements as toxic. While these can be toxic, the dose required to induce a toxic reaction is exceptionally high. As long as you’re not eating rock dust, toxicity from these stones is unlikely.

If you find any incorrect or inconsistent information in this table, please contact the IGS team.

This list is just a starting point. Please do your research and use caution when using crystals and be aware that all crystals pose risk as they are natural products. Any crystal can contain various compounds so care should always be taken to assume no crystal should be ingested or used for “potions” or elixirs to be ingested. Do not use any products from Mountain Aura to ingest or inhale unless directed from a licensed Physician.

Mountain Aura takes no responsibility for any injury caused by purchasing any product from www.mountainauracrystals.com or any affiliated social media site or in person event. By purchasing you accept responsibility that you are purchasing a natural product and understand the risks associated with that action.
