Generally, quartz crystals are safe to be washed with water. Crystals that are safe to be washed with water
While this is true, there are a few exceptions. It is often said that minerals cannot be cleansed in salt.
Quick bursts of water is fine with the crystals but submerging them for a long time will destroy them. The crystals will also release toxic chemicals into the water. You will notice they will slowly begin to loose its luster and just go into waste.Īny crystal that ends with -ite cannot be washed with salt water or water.
If you submerge the crystals mentioned above in water or salt water, they will eventually dissolve, since they contain iron and porous.
