Crystals are one of the most beautiful gifts that we have been given by Mother Earth and metals in their various forms can also delight the senses. However, just like Mother Earth herself, some crystals can be just as dangerous as they are beautiful. Many of these stones are perfectly safe to handle or wear as jewelry, but present a danger when they are used to create anything that will be consumed (internally).
No matter what you are intending to do with your crystals, you should always be aware of base minerals they contain as a very good chunk of them can contain poisonous elements, such as copper, lead, zinc and arsenic.
This can be a problem if you plan on using your crystals for Gem Elixirs.
A List of Potentially Toxic Minerals
Some minerals are more toxic than others and there are many different types of toxicity. You must use your own judgement when choosing what crystals to work with and how to use them.
This is NOT a comprehensive list of all toxic minerals.
Please be safe, and do extensive research on your crystals before using them, especially if you are making a Gem Elixir and the crystal infused elixir (water) will be ingested.
Adamite- Zinc arsenate, may also contain iron or copper
Actinolite - a fibrous form of asbestos
Ajoite - contains aluminum and copper
Alexandrite - contains aluminum
Aluminum - Aluminum toxicity can impair growth, cause bone deformities and weakness, confusion, speech problems and seizures. Especially dangerous for people with impaired kidney function.
Amazonite - The color is from copper or lead, but it is considered stable.
Angelite or Anhydrate - Calcium sulfate, may also contain lead
Antimony - Ingesting or inhaling antimony results in poisoning similar to arsenic
Aragonite - a type of calcium carbonite (aka chalk). Reactive to certain other minerals, releases toxic chemicals if burned. Irritating to eyes and mucus membranes.
Arsenic - A particularly potent poison popular with assassins during the 15th and 16th centuries.
Aspestos - causes respiratory irritation. A well-documented cancer-causing agent.
Atacamite - contains copper
Aurichalcite - a carbonate mineral containing zinc and copper
Azurite - contains copper
Barium - Affects the nervous system… explosive.
Beryl Group - beryllium aluminium cyclosilicate. Beryllium is a carcinogen

Brochantite - A copper sulfate
Cavansite - calcium vanadium silicate, All vanadium compounds should be considered toxic.
Celestite - strontium sulfate
