Unveiling the Mystique of Moonstone: History, Geology, and Spiritual Significance
Key takeaway: Moonstone is a feldspar gem known for its soft, floating glow, called adularescence. It is one of June's birthstones. It rates 6 to 6.5 on the Mohs scale, so it suits pendants, earrings and protected ring settings. It comes in white, grey, peach, blue and other colors. Sri Lanka and India are major sources. Its moon legends are folklore, but they add to its charm.
Who Is This Guide For?
This guide is for anyone born in June, or anyone who loves soft, glowing gemstones. It also helps buyers choosing between white, grey and peach moonstone. Use it when you are picking a moonstone ring, a gift or a piece with meaning.
What Legends Surround Moonstone?
Moonstone has fascinated people for centuries. Its soft, shimmering glow led to many legends. People once linked it to the Greek moon goddesses Selene and Phoebe. The Romans linked it to Luna and Diana.
Moonstone was treated as a charm for psychic insight and clairvoyance. It was said to spark passion and bring good fortune. It was also seen as a guardian for travelers and a calming stone for strong emotions. These are folklore and traditional beliefs, not proven effects.
What Is Moonstone Made Of?
Moonstone is a variety of feldspar. It forms from two feldspar minerals, orthoclase and albite. These grow in very thin, stacked layers. Light scatters between the layers. That creates the glowing sheen that seems to float across the stone.
Orthoclase is a common part of granite and similar rocks. It often forms large crystals in pegmatite veins. Without its glow, orthoclase has more everyday uses. It is used to make porcelain and as an ingredient in some scouring powders.
What Causes Moonstone's Glow?
The glow is called adularescence. It comes from light scattering off the thin layers inside the stone. Thinner layers give a blue sheen. Thicker layers give a white sheen. Cutters shape moonstone as smooth, domed cabochons to show off the glow.
What Colors Does Moonstone Come In?
Moonstone comes in many colors. You can find pink, yellow, green, brown, white, cream, grey, peach and blue. Blue-sheen moonstone is often the most valued. So-called "rainbow moonstone" is actually a variety of labradorite, a related feldspar.
Where Is Moonstone Found?
Moonstone is found around the world:
- Asia – Sri Lanka, Myanmar (Burma) and India.
- Africa – Madagascar and Tanzania.
- Elsewhere – Australia, Brazil, the United States and the European Alps.

What Do the Facts Say About Moonstone?
Each figure below comes from a recognized gemological source.
- Moonstone rates 6 to 6.5 on the Mohs scale, according to the Gemological Institute of America (GIA).
- Its glow comes from layered feldspar. GIA explains that thin layers of orthoclase and albite scatter light.
- Sri Lanka and India are key sources, according to GIA.
- Moonstone is a June birthstone. The American Gem Society lists pearl, moonstone and alexandrite for June.
- Quartz rates 7, according to GIA. That makes moonstone a little softer than amethyst or citrine.
What Did We Find When We Checked Our Collections for Moonstone?
I checked our gemstone earrings, freshwater pearl and bronze collections on 9 October 2026. Here is what we found:
- Gemstone earrings: none of the 46 pairs use moonstone.
- Freshwater pearl jewelry: 1 of 10 pieces uses moonstone. It is the Keishi Cornflake Pearl Necklace, at $1,825, with moonstone nuggets.
- Bronze rings: 12 of the first 48 bronze pieces are rings, priced $40 to $55. The moonstone tree branch rings shown above have sold.
Case Study: Why I Set Moonstone in Bronze Tree Branch Rings
In my experience, bronze brings out moonstone's softer colors. Its warm brown tone deepens grey moonstone and makes peach moonstone glow. At 6 to 6.5 on the Mohs scale, moonstone can chip in a ring. So I wrap each stone with bronze "branches" that rise around its edges. The branches act like a natural bezel and protect the stone from knocks. For bright white moonstone, I prefer sterling silver, which keeps the glow cool and clean.
How to Choose Moonstone Jewelry
- Glow – look for a sheen that moves across the stone as you tilt it.
- Clarity – clearer stones show a stronger, more even glow.
- Setting – choose bezel or protective settings for rings.
- Metal – silver suits white and blue stones, while bronze suits grey and peach.
How Should You Care for Moonstone?
- Clean it gently – use warm soapy water and a soft cloth.
- Skip ultrasonic and steam cleaners – they can crack feldspar.
- Avoid hard knocks – moonstone can split along flat planes.
- Store it apart – harder stones like quartz can scratch it.
