What Crystals Cannot Go in Water

July 21, 2021

When having a collection of crystals, it is important to remember that not all crystals can be cared for in the same way. For example, some crystals may not fare well in the sunlight-- others, may not be suited to the water. This is important to keep in mind for when you want to cleanse your crystals, display them or clean off any dirt or dust. After all, you want to appreciate and enjoy your crystals for as long as possible, I'm sure. Now, we know you might be wondering what crystals cannot go in water, of course-- so, we're here to help!

Crystals Below 5 on the Mohs Scale

A good rule of thumb to start is that any crystal that is rated a 5 or lower on the Mohs scale of hardness cannot go in water. Crystals at these levels may be too soft and could crack or even dissolve if left in water for any extended period of time. The Mohs Hardness Scale ranges from 1-10 and crystals are placed on the scale by determining which crystals or minerals they might be harder or softer than. When considering the water tolerance of crystals, the lower the stone is on the Mohs scale - or the softer it is, the more likely the stone will not be able to tolerate water.

Based on where they fall on the Mohs scale, you may want to avoid putting stones like Lepidolite (2-3 on the Mohs scale), Celestite (3-4 on the Mohs scale), and Fluorite (4-5 on the Mohs scale) in water. For any crystal you want to place in water, a good starting point is to determine where they fall on the Mohs scale.

Other Crystals that Cannot Go in Water

While knowing softer crystals cannot go in water, there are some harder stones that also are not water tolerant to keep in mind. Many of these stones should not be placed in water because of the minerals they contain, as water may damage them. For example, Tangerine Quartz should not be placed in water, as the iron oxide, which is what gives this gorgeous stone it's orange hue, could rub off, fade or turn a different color when exposed to water. Another stone that should not be placed in water is Hematite, as it may rust after coming into contact with water - again, due to the presence of iron oxide.

Caring for Crystals that are NOT Water-Safe

For crystals that are not water safe, thankfully, there are still some ways you can care for them. If you would like to purify those crystals, you might choose placing them in the moonlight or using sage instead of water to cleanse and purify them. This will ensure that there is no damage done to your treasured stones. For cleaning them, you might choose to delicately use a cloth to remove any dirt or debris. You will just want to be careful to not rub away any minerals present on the exterior of some stones, such as Tangerine Quartz. Some crystals may also tolerate a small amount of water when being spot cleaned, but you will want to be very careful if choosing to do this. Also, make sure that the crystal is dry of all water as soon as you are finished.
