Water Unsafe Crystals
Fluorite (especially SALT water)
Opal (although Australian Boulder Opal is generally safe, because it’s not porous)
This begs the question “What crystals can’t go in water?”
MOH Hardness: 3.5 Angelite will get damaged and eventually dissolve if you repeatedly expose it to water. Apatite is safe for a quick rinse, but don’t let it soak for hours. A few more things to take a look at are: azurite, azurite is a crystal that contains copper, celestite, desert rose, cinnabar, black tourmaline, fluorite, hematite, and calcite.
All crystals from the Quartz family such as Smokey Quartz, Clear Quartz, Rose Quartz, Citrine, Amethyst are safe to cleanse in water . Not all crystals are safe to be washed in water and knowing which ones are not water-friendly and may cause crystals to lose shine, density, or even completely dissolve with prolonged contact in water.
Is it safe to put crystals in water?
It is VERY important to keep in mind, however, that only some crystals can safely be placed in water, especially salt water – it can literally be a matter of mineral life, or death. Some minerals will lose their lustre, others may rust, and many will completely dissolve when submerged in water.
Is it safe to use water with quartz crystals?
Using water with quartz crystals is almost always harmless, with one exception: Tangerine Quartz. This is because the mineral that gives this quartz crystal its beautiful orange glow is iron oxide.
What gemstones should not be put in water?
Any that is a 5 or below on the Mohs harness scale should not be put in water. These gemstones dissolve or crack if left in water for an extended amount of time. Some harder gemstones should also be kept out of water. These include gemstones that contain minerals that can rust or can release toxins in water.
