Selenite: meaning, uses and care

How to read the labels Historical what the old sources say. Later tradition what later writers added. Modern modern practice and my own notes.

Selenite is one of the stones I suggest to beginners, and on this page I share what it really is, where its meanings come from, how witches use it today and how to look after it. Crystals are focus tools and beautiful objects, not medicine, and I keep that line clear throughout.

At a glance

What it is

Selenite is a form of gypsum, a soft mineral made of calcium sulfate and water. Gypsum is very common. It is the raw material of plaster and of most of the wallboard in our homes. Selenite is the name for its clear, glassy crystals, which can grow as flat plates or long blades.

Most of the “selenite” sold in crystal shops, especially the white, silky wands, towers and lamps, is actually satin spar, a fibrous form of gypsum with a pearly sheen. Some sellers use the two names interchangeably. Both are the same mineral, and both need the same careful handling.

Gypsum is soft: only 2 on the Mohs scale, so you can scratch it with a fingernail. It is also slightly soluble in water. A selenite wand left in water, or even in a damp bathroom, will lose its shine, become rough and eventually start to dissolve. This is the most important thing to know about this stone.

Selenite can also grow to astonishing sizes. In the Cave of the Crystals at Naica, in Mexico, miners found gypsum crystals more than ten meters long.

History and folklore

Historical The name selenite comes from the Greek selēnē, the moon, because of the stone’s soft, pale glow. In the ancient Roman world, clear gypsum crystals were split into thin sheets and used as window panes. Pliny the Elder described this “specular stone” in his Natural History, and the Romans mined it in Spain and elsewhere.

Modern In modern crystal books, selenite is linked with calm, clearing and light, and often with the moon because of its name. Many books claim that selenite “self-cleanses” and can cleanse other stones placed on it. These are modern beliefs. Its moon name is old; the energetic claims are new.

How witches use it today

Modern Selenite is a gentle, quiet stone in modern practice. Witches commonly use it to:

• Mark a calm space. A selenite wand on a shelf or a bedside table can mark a place for rest.
• Work with the moon. Because of its name, many witches place selenite on the altar for full moon and new moon work.
• Rest other stones. If you like the idea of a selenite plate for your other stones, it is a harmless and pretty way to store them. Keep it dry.
• Hold a quiet intention. Selenite is light and smooth, and it can be held during a short meditation.

A simple practice

1. On the night of a full moon, sit somewhere quiet with a selenite wand or plate.
2. Hold it gently, keeping your hands dry.
3. Breathe slowly and name one thing you would like more calm around.
4. Write that sentence in your journal with the date and the phase of the moon.
5. Return the selenite to a dry shelf, away from the bathroom and the kitchen sink.

Care: water and sun

Selenite needs more care than almost any other common shop stone.

• Never put it in water. Do not rinse, soak or wash selenite, and do not leave it out in dew or rain. Do not put it in moon water or drinking water.
• Keep it dry. Store it away from bathrooms, kitchens and windowsills where condensation forms.
• Dust it. Clean selenite with a soft, dry brush or cloth.
• Handle gently. It scratches, snaps and splinters easily. Thin wands can break into sharp pieces.
• Keep it from heat. Heat drives water out of gypsum and damages it. Do not leave it in hot sun or near a heater.
• Children and pets: keep small pieces and splinters out of reach.

Gentle cleansing, if you like it

Modern Cleansing and charging stones are modern practices, and the methods vary widely. The gentlest options suit every stone: ring a bell or a singing bowl nearby, or hold the stone, breathe on it softly and say your intention. Moonlight is harmless too, as long as you bring the stone in before the morning sun and keep it out of dew. Skip salt water, hot water and the freezer, which can damage or crack stones.

Stones, children and pets

Tumbled stones look like sweets to small children and toys to dogs, and they are a choking hazard. Keep your collection on a high shelf or in a closed box, and do not give stone jewelry to young children. If a child or pet swallows a stone, contact a doctor, a vet or a poison center.

Ethics and buying

Gypsum is abundant and widely mined, much of it for building materials, and selenite is usually inexpensive. That makes it easy to buy a lot of it without thinking.

• Buy what you will use. One small wand or plate is enough.
• Ask what it is. Ask whether a piece is selenite or satin spar, and whether it has been dyed or coated. Brightly colored “selenite” has often been dyed.
• Respect protected sites. Do not collect crystals from caves or protected areas.

An honest note

Selenite is soft, cheap and very beautiful, and its link to the moon goes back to its Greek name. The idea that it cleanses itself and other stones is modern and untested. The one thing everyone can agree on is that water ruins it. Keep it dry, dust it gently, and it will glow on your shelf for years.
