What Crystals are Water Safe?

Generally speaking, you should only cleanse crystals in water that are a 6 or above on the Moh’s hardness scale. The Moh’s hardness scale is a scale of 1-10 that measures crystals based on their hardness as well as the scratch resistance of minerals. 1 is the softest on the scale and 10 is the hardest. Although this scale is helpful, you cannot completely rely on it. Other factors are involved as well, like the iron content of crystals and porousness, or how much water the crystal can absorb. Also, there are some crystals that can become toxic when placed in water, like malachite (which should NEVER be put in water). Another good way to tell if a crystal ISN’T water safe is if it ends in -ite!
