Moonstone is a variety of feldspar you can spot by its bluish or milky glow, a sheen that seems to glide across the surface. That effect is called adularescence. Moonstone is the stone of gentleness, intuition and feminine energy, which is why it's one of the best-loved stones in moonstone jewelry. Here's everything you need to know: its geology, its legends, its meaning and properties, and how to wear it and care for it.
A feldspar with a moonlit glow
Unlike amethyst or clear quartz, moonstone isn't a quartz. It belongs to the feldspar family, the most common minerals in the Earth's crust. More precisely, it's orthoclase, a potassium aluminum silicate. Its gem variety goes by the pretty name of adularia, after the Adula massif in the Swiss Alps, where it was first described.
The finest stones have historically come from Sri Lanka. Its moonstones, with a blue sheen over an almost transparent body, are still the benchmark. India, Madagascar, Myanmar, Tanzania, Brazil and Australia are other notable sources, and each has its own shades: a milky, peach, gray or almost colorless body.
Adularescence: where does the glow come from?
Moonstone's charm is that veil of bluish-white light that moves as you tilt the stone, like moonlight on water. This optical effect, adularescence, comes from the mineral's inner structure. Very thin alternating layers of two feldspars scatter the light that passes through them. The thinner the layers, the bluer the glow. The thicker they are, the whiter and milkier it gets.
The body color ranges from white to gray, with peach, cream and brown tones in between. Cabochon cuts, with their domed, polished surface, show off the glow especially well.
A quick note in the name of transparency: the stone sold as "rainbow moonstone" is actually white labradorite, a cousin from the same feldspar family, with multicolored flashes. It's beautiful and natural, but it isn't adularia in the strict sense. It's worth knowing before you buy.
Origins: name and legends
The name is no accident. Since ancient times, people have linked this mineral to the moon and its light. The Romans saw a captured moonbeam in its glow and tied it to Diana, the huntress with the silver crescent. The Greeks linked it to Selene, the Moon herself, as their poets described her. In India, it's called chandrakanta, "beloved of the moon." It has always been treasured there as a good luck charm and is a classic gift between lovers.
Over the centuries, moonstone has kept coming back into fashion. It was a favorite of the Art Nouveau era, and today's designers have brought it back into the spotlight. It has never really left the display cases of gem lovers.
Moonstone meaning and symbolism
Moonstone is the stone of the feminine, of cycles and of intuition. Like the moon it's named after, it stands for what waxes, wanes and renews itself: your inner seasons, emotions that come and go, the patience it takes to start over. It's often linked to the sacral chakra, the center of emotions and creativity, and to the third eye chakra, the sixth, for its tie to intuition.
As a birthstone by sign, it's often named for Cancer and Pisces, two water signs known for being sensitive and intuitive.
Moonstone properties in crystal lore
In crystal lore, moonstone is known for calming the emotions and inviting gentleness. It's a stone of inner balance, the one people reach for in times of change or when they feel more sensitive than usual. It's a reminder that every cycle has its own rhythm.
It's also the stone of feminine energy above all others. It symbolically marks the big milestones in a woman's life and holds a top spot among the crystals for feminine energy and gentleness. Moonstone is linked to intuition and to small evening rituals, too. Many people keep one on their nightstand as a calming object, something gentle to look at before turning off the light. It doesn't promise more than that. The tradition tells its story, and the stone simply stays beautiful and keeps quiet watch by your bed.

How to wear moonstone
To keep moonstone close every day, wear it against your skin. A moonstone bracelet is the easiest way to start: its milky beads catch the light with every move. As a pendant close to your heart, a ring or earrings, its domed cabochon makes a statement while staying soft and subtle.

How to cleanse and care for moonstone
Moonstone is a little softer than quartz (6 to 6.5 on the Mohs scale). Keep it away from knocks and store it apart from harder stones that could scratch it. To clean it, just rinse it under running water and dry it with a soft cloth. Gently wipe the gaps between the beads, where dust likes to collect.
To keep its glow, let it air-dry away from radiators, then store it in its fabric pouch, away from perfume and lotions. And if you love a poetic ritual, set your beads on the windowsill on a full moon night, just for the pleasure of watching them catch the light. Avoid strong sunlight, though, since it could dull the glow over time. You'll find all our tips in our article on how to cleanse and care for your crystals.
