Collection: MOONSTONE

DON’T MISS THE GOOD STUFF AT THE BOTTOM!
Moonstone — The Stone of New Beginnings

Moonstone is one of the world’s most enchanting gemstones, admired for its soft, floating glow that seems to shimmer beneath the surface like moonlight dancing across still water. This captivating optical effect has inspired myths, legends, and admiration for thousands of years. Whether prized by mineral collectors, jewelry enthusiasts, or those drawn to its calming appearance, moonstone remains one of the most recognizable and beloved members of the feldspar family.

AKA

• White Moonstone
• Rainbow Moonstone* (technically a variety of labradorite, not true moonstone)
• Adularia (historic trade name for high-quality moonstone)
• Hecatolite (an old, rarely used trade name)

Why Collectors Love It

Collectors treasure moonstone because no two pieces display exactly the same glow. The famous bluish-white sheen—known as adularescence—appears to drift across the stone as it moves in the light, creating an almost magical effect.

Moonstone ranges from crystal-clear material with vivid blue flashes to creamy white, peach, gray, green, champagne, and even rare black varieties. High-quality specimens displaying strong blue adularescence are especially prized by collectors.

Localities

Moonstone is found around the world, though certain deposits are especially famous for producing exceptional material.

Notable localities include:

• Sri Lanka (world-famous for fine blue moonstone)
• India (rainbow, peach, gray, and white varieties)
• Madagascar
• Myanmar (Burma)
• Tanzania
• Australia
• Brazil
• Norway

• Austria
• United States (Virginia, New Mexico)

Sri Lankan moonstones are widely regarded as producing some of the finest blue adularescence ever discovered.

Geological Formation

Moonstone forms deep within cooling magma where feldspar-rich minerals slowly crystallize over millions of years. As orthoclase and albite feldspars cool, they separate into microscopic alternating layers.

These incredibly thin internal layers scatter incoming light, producing the signature glowing phenomenon known as adularescence.

The slower the cooling process, the better developed these internal structures often become, resulting in stronger optical effects.

Mineralogy Information

Moonstone is a variety of orthoclase feldspar composed of alternating microscopic layers of orthoclase and albite.

Its shimmering appearance is not caused by inclusions but by light interference within these microscopic internal structures.

The finest moonstones display:

• Strong blue floating sheen
• High transparency
• Minimal fractures
• Excellent polish
• Even body color

Unlike many gemstones that sparkle through crystal faces, moonstone creates beauty through internal optical physics.

Key Features

• Floating blue or white glow
• Soft pearly appearance
• Translucent to transparent body
• Smooth cabochon polish highlights adularescence
• Elegant neutral color palette
• Naturally calming visual character
• Excellent for jewelry and display

The Geological Era

The feldspar minerals that make up moonstone have formed throughout much of Earth’s geological history.

Many commercially mined moonstones crystallized during tectonic and volcanic activity occurring from the Precambrian through the Cenozoic Era, depending on the deposit. Individual specimens may be tens to hundreds of millions of years old.

Mineral Class

Class: Silicates

Group: Feldspar

Moonstone belongs to the feldspar group, the most abundant mineral family in Earth’s continental crust.

Rock Formation

Moonstone most commonly forms in:

• Granite pegmatites
• Granitic intrusions
• Syenites
• Feldspar-rich igneous rocks
• Metamorphic environments derived from feldspar-rich rocks

Weathering eventually releases moonstone crystals, allowing them to accumulate in secondary deposits where they are mined.

Level of Rarity

Moonstone itself is relatively common, but premium collector-quality material is considerably rarer.

Generally:

• Common white moonstone: Common
• Peach moonstone: Fairly common
• Gray moonstone: Moderately uncommon
• Black moonstone: Uncommon
• Strong blue flash moonstone: Rare
• Highly transparent blue adularescent moonstone: Very rare and highly collectible

Large flawless specimens with intense blue glow command premium prices.

Historical and Folklore Stories

Moonstone has captivated civilizations for thousands of years.

Ancient Romans believed moonstone was formed from frozen moonlight and associated it with the lunar deities.

In Hindu tradition, moonstone has long been considered sacred and believed to carry blessings, wisdom, and good fortune. It was often presented as a wedding gift or cherished family heirloom.

Across Europe during the Middle Ages, moonstone was thought to help travelers journey safely under the light of the moon and was believed to reveal hidden truths.

During the Art Nouveau movement of the late 1800s and early 1900s, master jewelers such as René Lalique frequently featured moonstone in elaborate artistic jewelry, helping establish its reputation as one of the world’s most elegant gemstones.

Today, moonstone continues to symbolize hope, transformation, and life’s changing seasons.

Metaphysical Nod

Many believe moonstone encourages emotional balance, intuition, inner peace, and fresh beginnings. It is often associated with embracing life’s natural cycles, trusting one’s instincts, and welcoming personal growth with grace.

Many associate moonstone with:

• New beginnings
• Emotional harmony
• Feminine energy
• Intuition
• Inner wisdom
• Compassion
• Self-discovery
• Calm reflection

Associated Chakras:

• Crown Chakra
• Third Eye Chakra
• Sacral Chakra (particularly peach moonstone)

Suggested Mantras:

• “I welcome each new beginning with confidence.”
• “My intuition guides me wisely.”
• “I trust the natural rhythm of my life.”
• “Peace flows through me like moonlight.”

Display and Care Instructions

Although moonstone is durable enough for jewelry, it should still be handled with care due to its perfect cleavage.

For best care:

• Store separately from harder gemstones.
• Clean using warm water, mild soap, and a soft cloth.
• Avoid ultrasonic and steam cleaners.
• Protect from sharp impacts.
• Keep away from harsh household chemicals.
• Display away from prolonged direct sunlight to help preserve its appearance.

A soft microfiber cloth is ideal for maintaining its beautiful glow.

How to Spot a Fake

Because moonstone is popular, imitation materials are common.

Signs of genuine moonstone include:

• A soft floating glow that moves beneath the surface.
• Natural internal inclusions or slight imperfections.
• Gentle, layered adularescence rather than glitter.
• Cool feel when first held.
• Slight variation in color and transparency.

Possible indicators of imitation:

• Glitter that looks painted on the surface.
• Uniform, artificial-looking flash.
• Plastic-like warmth and light weight.
• Air bubbles inside the material.
• Extremely low prices for supposedly premium blue-flash specimens.

Also note that “Rainbow Moonstone” sold in the jewelry trade is actually a variety of white labradorite rather than true orthoclase moonstone.
