Can Black Tourmaline Go In Water? (Water Safety & Cleansing)

Can black tourmaline go in water?

Black tourmaline is a protective stone – but is it water-safe? Keep reading to find out whether black tourmaline can go in water, along with tips for how to cleanse it.

Is Black Tourmaline Water Safe?

Black tourmaline is a hard gemstone that’s rated as 7-7.5 on the Mohs Hardness scale, so it’s safe to cleanse in running water for short periods.

You shouldn’t leave it submerged for a long time, however, as this could damage some of the elements that form the crystal’s structure. Black tourmaline is also not suitable for making crystal infused drinking water.

Black Tourmaline Hardness and Why it Can Go in Water (for Short Periods)

Black tourmaline rates at 7-7.5 on the Mohs Scale of Hardness. This makes it harder than many other crystals, including Rhodonite and Selenite, but softer than topaz or beryl.

Water is dangerous for crystals rated at 5 or below on the Mohs Hardness Scale, so black tourmaline is safe to cleanse in water. It’s not water soluble and won’t dissolve or crack, as long as you only use cold or lukewarm water.

Hardness isn’t the only consideration when deciding whether a crystal is water-safe though. You also need to think about the chemical composition, and whether any of the crystal’s elements can rust or dissolve in water.

Black tourmaline has a complex structure that may contain traces of manganese, titanium, iron, and various other components. While none of these elements will dissolve in water, some may rust if left in water.

For this reason, I don’t recommend submerging black tourmaline for long periods. Instead, use short bursts of running water to cleanse or clean this crystal, then dry it with a soft cloth.

Can Black Tourmaline Go in Salt Water?

Black tourmaline can withstand salt water for short periods, but that doesn’t mean it’s a good idea to expose it to this type of liquid.

Salt water has abrasive and corrosive properties, as particles of salt can work their way into tiny cracks in the stone’s surface. Extended or repeated exposure to salt water could cause a black tourmaline crystal to fade or split.

So, to prevent damaging your stone, I recommend avoiding salt water when cleansing a black tourmaline crystal. Fresh water can be just as effective at cleansing without the corrosive properties of salt.

Can Black Tourmaline Go in Moon Water?

Yes, black tourmaline can go in moon water for short periods, as this is chemically the same as fresh water.

Don’t leave black tourmaline in moon water for extended periods though, as this may cause damage and rusting.

Can Black Tourmaline Be Used in a Water Elixir?

Crystal infused water is a popular method for increasing the potency of a stone’s healing properties. Only certain stones are safe for infusing water though.

As black tourmaline has a complex chemical structure containing many different elements, I don’t recommend using it to create a crystal elixir. Some of these elements may be unsafe to drink, so it’s important that they don’t dissolve into the infused water.

Indirect Method for Creating Black Tourmaline Infused Water

While black tourmaline is not safe for directly infusing water, you can still use the “indirect” method of crystal infusion:

  1. Cleanse and charge the black tourmaline stone to restore its healing properties.
  2. Seal the black tourmaline stone inside a jar with a lid.
  3. Place the sealed jar inside a larger bowl, then fill this larger bowl with water.
  4. Cover the bowl and allow time for the water to indirectly infuse.
  5. Drink the infused water soon after, unless you are planning to add a preservative.

The most important thing is that the black tourmaline crystal never comes into direct contact with the water. Make sure the glass container is properly sealed and waterproof.

How to Cleanse Black Tourmaline in Water

Black tourmaline is a protective crystal that absorbs negative energy from its surroundings. It’s important to regularly cleanse it to remove unwanted energies.

Submerging a black tourmaline stone for long periods could cause damage, so here’s a safer water cleansing method:

  1. Find a source of running water. Natural water in streams or rivers is best, but tap water can also be effective for cleansing. Avoid powerful streams of water, such as from an electric power shower.
  2. Hold the black tourmaline stone in the stream for 1-2 minutes. Focus on your intention to cleanse the stone during this time.
  3. Remove the stone from the water stream and dry it with a microfiber cloth. As black tourmaline has a ridged structure, make sure to (gently) use the cloth to dry water in the crevices.
  4. Leave the black tourmaline crystal in a well-ventilated area to finish drying.

Alternatively, you could use a dry cleansing method. Examples include visualisation, smudging, and moonlight. Click here to learn more about the various ways to cleanse a healing crystal.

Can You Clean Black Tourmaline?

Black tourmaline can be cleaned using warm water and a small amount of soap. Make sure the crystal is completely dry afterwards by using a soft cloth and allowing time for any remaining water to evaporate.

Don’t use hot water when cleansing or cleaning black tourmaline. Sudden changes in temperature could cause the crystal to crack.


Black tourmaline is a protective crystal that rates as 7-7.5 on the Mohs Scale of Hardness. This means it’s a relatively hard stone that won’t dissolve if it comes into contact with water for short periods of time.

Long exposure to water can still be damaging to black tourmaline though. It has a complex chemical structure that includes a range of different elements, including some that are prone to rusting.

To prevent damage, I only recommend running black tourmaline under cool or lukewarm water for 1-2 minutes when cleansing. Make sure you dry the stone with a soft cloth and allow time for it to fully dry.
