4 min read

Despite the growing popularity of crystal-infused water, a large number of crystals are actually unsafe for direct contact with drinking water. This poses significant health risks, as some stones can leach toxic substances into the water. Understanding which crystals are safe and which are not is crucial for anyone interested in this wellness practice.

Quick Summary

This guide explains the critical safety factors for making crystal water, including identifying toxic stones and the risks of direct infusion. It details the safest methods for creating crystal elixirs and provides a list of common safe versus unsafe crystals to help you make informed and healthy choices.

Key Points

Not All Crystals Are Safe: Many common crystals contain toxic minerals like copper or lead and can leach into water if submerged.
Beware of Soft or Treated Stones: Crystals with a Mohs hardness below 6, along with porous or dyed stones, can break down or release harmful substances.
The Safest Method is Indirect Infusion: Place the crystal in a sealed glass tube or jar within the water, allowing energy to transfer without physical contact.
Research Before You Infuse: Always verify the specific crystal's water safety and chemical composition before use, as anecdotal evidence is insufficient.
Maintain Hygiene: Regularly clean your crystals and change the water to prevent bacterial growth and ensure safety.
Prioritize Health: If in doubt about a crystal's safety, use the indirect method or consult a professional, and stop use immediately if you experience adverse effects.

Why not all crystals are water safe

While the concept of imbuing water with the energy of crystals is ancient, modern practitioners must approach it with a solid understanding of geology and chemistry. The primary risk is that certain minerals contain toxic elements that can leach into the water when submerged. These elements, including copper, lead, and arsenic, can be harmful or even poisonous if ingested. Additionally, some crystals are not stable in water; they can dissolve, rust, or break down, which can also release harmful particles.

Factors that determine crystal water safety

Several key factors determine whether a crystal is safe for direct water infusion:

Mohs Hardness Scale: This scale measures a mineral's ability to resist scratches. Crystals below a 6 on the scale are generally considered too soft for water immersion, as they can dissolve or degrade over time.
Chemical Composition: The mineral's chemical makeup is the most important factor. Crystals containing toxic metals like copper (e.g., malachite, amazonite) or lead (e.g., galena) are highly dangerous. Sulfide minerals like pyrite can also produce sulfuric acid when exposed to water.
Porosity: Porous crystals, such as turquoise, can absorb water and harbor bacteria within their structure. They can also degrade and release particles.
Treatments: Some crystals are dyed, coated, or stabilized with resins or other chemicals. These treatments can leach into the water and should be avoided for direct infusion.

The safe alternative: Indirect infusion method

For anyone wanting to create a crystal elixir with a stone that is not water safe, the indirect infusion method is the ideal solution. This technique allows the water to be charged by the crystal's energy without any physical contact, eliminating all risk of contamination.

How to perform the indirect method:

Select your setup: Choose two clean glass containers. A large glass bowl or pitcher for the water, and a smaller, sealed jar or test tube for the crystal.
Prepare your crystal: Cleanse your chosen crystal and place it inside the smaller, sealed container. Ensure the seal is watertight.
Place the crystal container: Submerge the sealed container with the crystal inside the larger container filled with filtered or spring water.
Infuse and remove: Allow the water to infuse for several hours or overnight. The energetic vibrations are believed to transfer through the glass. When ready, remove the inner container and enjoy your safe crystal elixir.
