Others: feathers, blowing, sesame oil, wiping cloth, bells, music, drums and chanting. Some stones that don't like sunshine: calcite, fluorite, amethyst, hibiscus crystal, aquamarine, amethyst, kunzite, spodumene and kyanite. Some rocks that don't like water: rock, gypsum, angel stone, sulfur, lepidolite, anhydrous gypsum, kyanite, rainbow hematite, kyanite, apophyllite, kyanite, chrysocolla, malachite (toxic in water). Some stones that don't like smoking: If you use sage or incense, make sure the stones move on or around burning objects; Or let smoke rise from burning materials and let stones move in the smoke. Porous/concave stones may turn yellow or brown because they absorb too much smoke during purification.
