Crystals
A Beginner's Guide to Crystals and Their Meanings
For thousands of years people have treasured beautiful stones as talismans, gifts and reminders. This guide covers 15 popular crystals, what they actually are, the meanings traditionally given to them, how to care for them, and how they pair with the moon's phases and the tarot.
A gentle note: we share crystals as a spiritual and reflective practice: objects that help you pause, focus and remember an intention. They are not a treatment for any physical or mental health condition, and nothing here is medical advice.

How to cleanse and charge crystals
"Cleansing" a crystal is a symbolic reset: a moment to clear the stone of what it has been "holding" and give it a fresh purpose. "Charging" means pairing it with a new intention. There is no single right method, and none needs to cost anything. Choose the one that suits the stone.
- Moonlight (gentlest, works for almost every stone). Set crystals on a windowsill or outdoors overnight on the full moon, or on any night of the waxing moon. Bring them in before strong morning sun, which can fade amethyst, rose quartz and citrine. Check the next full moon on our moon page.
- Moon water. Make moon water, then dab a few drops on water-safe stones (quartz, amethyst, carnelian) or simply set the stone beside the jar. Never soak selenite, lapis lazuli or pyrite.
- Sound. Ring a bell, singing bowl or chime near your stones for a minute. Safe for every crystal.
- Smoke or breath. Some people pass stones through incense or herb smoke from plants they grow or buy responsibly; others simply breathe slowly over the stone with intention.
- Earth. Bury a hard, water-safe stone in a pot of soil overnight. Avoid soft or porous stones.
- Charge with an intention. Hold the stone, name one intention in a sentence, and keep it somewhere you'll see it. Many people do this at the new moon and check in at the full moon.
A full moon charging ritual
On the night of the full moon, lay your crystals on a clean cloth near a window. Write what you are grateful for this cycle, then one thing you're ready to release. Place the paper under the stones overnight. In the morning, choose one stone to carry for the next two weeks as a reminder. Pair it with our full moon release ritual.
Crystals for each moon phase
A simple way to use your collection through the month. See tonight's phase on the moon page.

Care and safety
- Know your stone's hardness. Stones below about 6 on the Mohs scale (selenite, lapis lazuli, obsidian, malachite) scratch easily and don't like water. Store soft stones separately.
- Don't drink crystal "elixirs" made by soaking stones. Some minerals, such as malachite, contain copper or other toxic elements, and some stones dissolve. If you like the idea, set the stone beside a glass of water instead.
- Sun fades color. Amethyst, rose quartz, citrine and some aventurine can fade with long exposure to direct sun.
- Buy thoughtfully. Ask sellers where stones were mined and whether they are dyed, heat-treated or lab-grown. Much "citrine" is heated amethyst, and bright-blue "howlite" is often dyed.
- Keep small stones away from young children and pets. They can be a choking hazard.
