- Gemstones that never need cleansing: kyanite, citrine, Super Seven, and selenite.
Additional ways to cleanse gemstones:
- Use large quartz clusters to cleanse smaller gemstones.
- Carnelian can cleanse other crystals; cleanse carnelian after each use.
- Cleanse gemstones in fresh or dried flower petals for 24 hours.
- Clear gemstones under running water or natural water sources. Some gemstones are water soluble and cannot be cleansed in water. Water will damage or dissolve the following gemstones: calcite, gypsum, selenite (all forms), halite, pyrite, optical calcite, malachite, hematite, magnetite, lodestone, and turquoise.
- Plants cleanse gemstones. Place crystals on top of or bury in soil for 24 hours.
- Sunlight cleanses gemstones, and some gemstones are photosensitive. The following gemstones will fade in sunlight: amethyst, fluorite, rose quartz, calcites, ametrine, aquamarine, celestite, kunzite, opal, prasiolite, smoky quartz, and topaz.
- Coarse, dry salt crystals are commonly used to cleanse gemstones for up to 24 hours. Due to the abrasive nature of salt, take caution with softer crystals. If salt is used to cleanse, rinse crystal well with pure water and dry thoroughly with a soft cloth. Avoid using salt with friable crystals. In humid climates, salt crystals may cause damage to gemstones over time. Salt can get stuck in gemstone crevices, and if combined with water molecules in humid air, may split the crystal. Avoid using salt to cleanse the following: calcite, carnelian, hematite, labradorite, spectrolite, lepidolite, magnetite, mica, moldavite, opal, turquoise, ulexite, and most gemstone clusters.
- Soak crystals in brown rice for 24 hours. Bless the rice, cook, and eat the rice. If toxic gemstones were used, dispose of brown rice.
- Handle with care. Detailed list of potentially toxic gemstones.
- Sensitive gemstones are softer and scratch easily. Minerals with a hardness below five are easily scratched by quartz; consult the Mohs hardness scale.
- Keep the following softer gemstones separate or protected from other crystals: fluorite, aventurine, selenite, malachite, turquoise, celestite, and chyrsocolla.
- Do not use jewelry polishing cloths on the following: amber, coral, emerald, ivory, jadeite, lapis lazuli, malachite, opal, and pearls.
