What it evokes
In modern crystal practice, moonstone is linked to renewal and love: it is said to be chosen to mark a beginning, a change of rhythm, or as a gift of tenderness.
This reading rests on its look. Its bluish glow, sliding beneath the surface, recalls the moon, and this resemblance fed very old beliefs. Pliny already describes a white stone bearing the image of the moon according to its phases, though we do not know whether it is the same stone. Kunz reports that in India it was held to be a sacred stone and that, for lovers, it was believed able to awaken tenderness.
Today it is taken as a support: a piece of jewelry worn at the new moon, to recall a resolution you want to renew.
The traditions
- Rome, 1st century
Pliny describes selenitis, from Arabia: white, translucent, with a honey-colored sheen, it is said to contain an image of the moon that follows its phases. Nothing proves that he is speaking of today’s moonstone, a feldspar: the Greek name comes from selênê, the moon.
Pliny the Elder, Natural History, XXXVII, 67 (Littré translation) - India and Europe, according to Kunz
According to Kunz, moonstone was held to bring luck and to be sacred in India, where it was shown for sale only on a yellow cloth, the sacred color. It ranked high as a lovers’ gift, and lovers were believed able, by placing it in the mouth at the full moon, to read their future.
Kunz (1913), chapter “Moonstone” - 1913 and the 1912 list
Kunz places moonstone among the phenomenal stones, as the stone of Monday, the day of the moon. The list adopted in 1912 by American jewelers gives it as the alternative stone for June, in place of the pearl.

A gestureWear it as a ring or necklace, or set it by the bed on a new moon evening, to mark a fresh start.
No stone has a proven effect on health: if you have a health concern, see a health professional.

Nuances and sources
According to the books, it is linked to Cancer, and sometimes to the crown or the brow among the chakras: these correspondences are recent and diverge. The name “rainbow moonstone” often designates a white labradorite, and “opalite” an opalescent glass.

Moonstone: your questions
How can you tell a real moonstone?
A real moonstone shows a bluish sheen that glides as you turn it, often with fine internal fissures. Opalescent glass, sold as opalite, has a uniform milky luster and may contain round bubbles. White labradorite, with multicolored reflections, is also sold under this name. Only a laboratory can settle it.
Is moonstone fragile?
It resists everyday scratches (6 to 6.5 on the Mohs scale), but its easy cleavages make it brittle: a sharp blow can split it in two. Keep it in a separate case and wash it simply in lukewarm water with a soft cloth.
Can you leave it in the moonlight?
Yes, moonlight harms no stone. Nothing measures a “recharge”: it is a traditional gesture, chosen for the pleasure of the ritual. If you expose it to the sun, avoid long hours in a shop window and direct heat.
