Labradorite: The Stone of Flash and Fire

Labradorite is the stone that fools you. From one angle it looks dull, almost gray, like a piece of asphalt. Tilt it a quarter inch. Suddenly there is a flash of peacock blue, or gold, or green, or violet, sliding across the surface. Tilt it back and it is gray again. People who see this for the first time usually stop and stare. We see this at the counter most days.

We are James and Deborah, and we have run Crystal Empire Gems in Grass Valley, California since 2015. James uses labradorite in pendants more often than almost any other stone, and we keep a steady stock of polished slabs, tumbled pieces, and rough specimens. This is the long version of what labradorite is and why the flash happens.

What labradorite actually is

Labradorite is a member of the plagioclase feldspar group. Like moonstone, it is a feldspar, but the flash works differently. Labradorite shows a flash effect called labradorescence, which is caused by light interacting with thin alternating layers inside the stone. Different layer thicknesses produce different flash colors. A piece with thin layers flashes blue. A piece with thicker layers flashes gold.

This is not a coating. It is not a stain. The flash is part of the internal structure of the stone, formed over millions of years as the rock cooled slowly underground. When light enters the stone, certain wavelengths bounce off these internal layers and produce the moving color. The effect is similar to how a thin film of oil on water shows shifting color.

Labradorite sits at Mohs 6 to 6.5 on the hardness scale. That is the same as moonstone. It is hard enough for pendants and earrings but softer than ring stones meant for daily wear. The body of the stone is usually dark gray, sometimes nearly black, with the flash hiding inside until the angle is right.

Where labradorite comes from

The stone is named for the Labrador region of Canada, where it was first identified by European naturalists in the late 1700s. The Inuit and other Indigenous peoples of the region had known about it for much longer. Canadian labradorite, called Lab grade or sometimes simply Labrador material, is still mined today and produces beautiful classic blue-gold flash.

Madagascar is now the largest commercial source of labradorite. Madagascan material tends to have a slightly purer flash and is the most common in the trade. Finland produces a rare variant called spectrolite, which shows flash in the full spectrum of colors on a single piece. Spectrolite is more expensive than regular labradorite and is sometimes called the king of feldspars.

Other sources include Russia, Mexico, Australia, and the United States. Each region has slight variations in color, body tone, and flash strength.

How people have used labradorite across history

Inuit legend tells that the northern lights were once trapped inside the rocks along the coast of Labrador, until a warrior struck the stones and freed most of the lights into the sky. The labradorite that remained is said to still hold a piece of the aurora. Whether or not the story is literally believed, it captures something true about the stone. The flash really does look like the northern lights in miniature.

In European folklore from the 1800s onward, labradorite has been associated with transformation, intuition, and protection. The stone became popular in Art Nouveau jewelry alongside moonstone. In modern crystal practice, it is often called a stone of magic, change, and inner work.

How people use labradorite now

Most of our customers buy labradorite for one of three reasons. They are drawn to the flash and want it as a beautiful object. They want a pendant to wear because the dark base color works with any outfit. Or they use it in traditional practice for moments of change and transition. Our piece on crystals for new beginnings covers the change-and-transition family in more depth.

We do not make medical or psychic claims about labradorite. We will not promise that wearing the stone will sharpen your intuition or open hidden senses. What we will say is that people have associated labradorite with thresholds and transitions for as long as it has been known, and many find it a useful companion in moments of change. The stone helps you pay attention. You do the rest.

Buying labradorite: what to look for

Flash strength is the first and most important thing. A good piece flashes from multiple angles. A weak piece only flashes from one specific angle and goes dead the moment you move. Tilt the stone in the light before you buy. The flash should chase the light.

Flash color is next. The most common flash is blue. Gold is rarer and often more valued. Green, violet, and orange flashes are less common still. Spectrolite, with multiple colors on one piece, is the most prized. Stones with strong purple flash sometimes go by the trade name purple flash labradorite.

Body color matters less than flash. A dark gray body with bright flash is excellent. A nearly black body with a single bright stripe of flash, sometimes called a wing, is also prized. Avoid pieces where the body is so light that the flash washes out.

Size scales with price. Large polished slabs cost more. Hand-sized chunks with strong flash are usually moderate in price. Tumbled stones are very affordable but can lose some of their flash because the rounded surface scatters light differently than a flat polished face.

Caring for labradorite

Labradorite is reasonably hardy but softer than quartz. A brief rinse in water is fine. Avoid harsh cleaners and ultrasonic machines, which can travel along internal cleavage planes. Our guide on cleansing crystals covers safe methods. Moonlight, smoke, sound, and selenite contact all work well.

Store labradorite away from harder stones in a soft pouch. The polished surface scratches if it sits loose in a drawer with quartz, agate, or other harder pieces. Direct sunlight does not fade labradorite the way it fades amethyst, but it does not improve it either. Indirect light is best.

Labradorite in jewelry

James uses labradorite constantly in his work. The dark body color works with sterling silver and copper wire equally well. He prefers bezel settings or wire wraps that hold the stone securely without covering the flashy face. Pendants and earrings are the most common uses. Our wire-wrap guide covers the craft in more detail if you are curious about how a labradorite gets turned into a pendant.

Pairing labradorite with other stones

Labradorite is often paired with moonstone because the two feldspars complement each other. Moonstone offers a soft, bright presence. Labradorite offers depth and drama. Many of our customers also pair labradorite with clear quartz for clarity, or with smoky quartz for grounding through a transition. There is no required pairing. A single labradorite piece does the work most people want from the stone.

Come see the flash

If you are in Grass Valley, come hold a piece. Photographs do not capture labradorite. The flash on a good Madagascan slab or a Finnish spectrolite piece has to be seen in person, in motion, in real light. We have a wide selection in the case. We will turn pieces for you. The shop is at 139 Mill Street.

Quick FAQ

Why does labradorite flash?

Thin alternating internal layers scatter light and produce the moving color. The effect is called labradorescence.

What is spectrolite?

A rare variety of labradorite from Finland that shows flash in multiple colors on one piece. It is more expensive than regular labradorite.

Can labradorite be worn daily?

In pendants and earrings, yes. Daily-wear rings will show wear because labradorite is softer than typical ring stones.

Will labradorite fade in sunlight?

Not significantly. Indirect light is still preferred for long-term storage.
