Frequently Asked

Honestly, the evidence is mostly traditional and personal. Controlled studies of crystal healing have generally found placebo-level effects, which is to say the effect is real for many people even if the mechanism is not what the tradition claims. We write about crystals the way a working practitioner would, with traditional associations clearly labeled and mineralogy kept separate. Use the stones as focusing tools and trust your own experience.

The two safest, universally suitable methods are sound (a singing bowl or a clear voice held on a single note for 30 to 60 seconds near the stone) and smoke (sage, palo santo, or simple incense passed around the stone). Salt and direct sun can damage some stones. See the cleansing methods index for what is safe for which stone.

Anything below Mohs 5, anything fibrous, and anything water-soluble. That includes selenite (dissolves), malachite (toxic dust if it powders), pyrite (rusts), lapis (the pyrite inclusions react), turquoise (porous), kyanite and many of the softer copper minerals. When in doubt, do not bathe the stone, wipe it with a damp cloth instead.

Amethyst, rose quartz, citrine, fluorite, kunzite, celestite, smoky quartz, and most colored quartz varieties. The color centers in these stones are damaged by UV. Moonlight is always safe, which is one reason the tradition uses it for charging.

For common stones, hardness, density, and how light moves through the stone are the giveaways. Glass is lighter than quartz at the same size; dyed howlite (sold as turquoise) is softer than real turquoise; resin fakes are warm to the touch, real stone is cold. If you buy from a reputable lapidary or rock shop, fakes are rare. If a stone is suspiciously cheap or suspiciously perfect, ask questions.

Chakra is a Sanskrit framework that maps energy centers along the spine, each with an associated color and quality. The crystal tradition borrows the color associations and uses them as a quick way to organize stones by intention, a green stone for the heart, a yellow stone for the solar plexus, and so on. The map is a tool for memory and practice, not a literal claim about anatomy.

Three to five is plenty for a starting practice. We recommend a clear quartz (the universal amplifier), a black tourmaline or smoky quartz (grounding and protection), a rose quartz (heart), and one stone tied to a goal you are working on. Add a selenite slab for cleansing the rest and you have a full kit. Bigger is not better.

Most crystals are restful or neutral in a bedroom. The exceptions are stones the tradition considers stimulating, carnelian, red jasper, and bright citrine, which some sensitive sleepers find too active near the bed. Amethyst, lepidolite, howlite, and rose quartz are the classic bedroom stones. If a new stone is keeping you up, move it to another room and notice.

For ritual rhythm and for charging. New moons are for setting intentions; full moons are for charging stones by moonlight and for gratitude practice; waning moons are for releasing. Tonight's moon page shows the current phase and what the tradition does on a night like this.

Mineralogical fields (formula, hardness, crystal system, luster, colors) come from public mineralogical references including Mindat and Wikipedia. Metaphysical associations are drawn from working crystal-healing literature and refined by our editors. We do not invent properties; if a claim is contested in the tradition, we say so on the page.
