What Is Labradorite? A Friendly Guide to the Stone

Labradorite is a feldspar mineral with a reputation for surprise. Most pieces look grey, dark or brownish until you turn them, and then a blue, green, gold or violet flash appears from inside the stone. That flash is the reason people notice labradorite in the first place, and it is also the reason photographs rarely do it justice.

The name comes from Labrador in Canada, where the stone was described in the late eighteenth century. It is not a rare mineral in the way that, say, diamond is rare, but good labradorite with a strong, even flash is still a pleasure to find. This guide explains what labradorite is, why it flashes, how to choose a piece and how to look after it, with the traditions around it kept clearly in the realm of story and belief.

What Labradorite Actually Is

Labradorite is a variety of plagioclase feldspar, one of the most common mineral groups in the Earth’s crust. Feldspars make up much of granite, basalt and many other rocks, but labradorite is valued for a particular optical effect rather than for forming neat, geometric crystals. Most labradorite you see in shops is massive or blocky, cut and polished from larger pieces, though small crystal faces can occur.

Chemically, it sits within the plagioclase series, between albite and anorthite. The label labradorite is used for material in a particular compositional range, and also more loosely for feldspar with a strong flash. That looseness is worth knowing: not every stone sold as labradorite would be classified the same way in a geology lab, but the look people recognise is usually the same.

• Mineral family: plagioclase feldspar
• Hardness: about 6 to 6.5 on the Mohs scale
• Typical look: grey, dark grey, blackish or brownish base with flashes
• Name origin: Labrador, Canada

Why Labradorite Flashes

The flash is called labradorescence. It is not a pigment or a coating. It comes from light interfering as it reflects from tiny internal layers within the stone. These layers are related to the way the feldspar separated into slightly different compositions as it cooled. When the layers are just the right thickness, certain colours are reinforced and others cancel out, so you see blue, green, gold, orange or violet depending on the angle.

Labradorescence is directional. A piece can look dull from one side and suddenly light up when you turn it. That is normal, and it is one reason photographs can be misleading. The best way to judge a stone is in person, moving it gently under ordinary light. Strong shop lighting can make a modest flash look dramatic, so it helps to look again in softer light.

• Blue is common; gold, green, orange and violet also occur
• The flash changes with angle
• A smooth polished surface shows it best
• It is not the same as chatoyancy or adularescence

Labradorite, Spectrolite and Other Lookalikes

Spectrolite is a trade name for a particularly striking labradorite, usually from Finland, with a full spectrum of colours. It is not a separate mineral species. Some people use spectrolite loosely for any very colourful labradorite, so ask what the name means in a particular shop.

Labradorite can be confused with other iridescent feldspars, such as moonstone, which usually has a softer blue or white sheen called adularescence. It can also be confused with dyed or coated stones. A genuine labradorite flash usually appears to come from inside the stone and shifts as you turn it; a coating tends to sit on the surface and can look uniform or scratched. If a piece is unusually vivid, it is fair to ask whether it has been treated.

• Spectrolite: a trade name, not a separate species
• Moonstone: usually softer, with a milky sheen
• Coated stones: the flash may look surface-bound
• Ask about treatments if you are unsure

Choosing a Piece You Will Enjoy

There is no single best labradorite. Some people prefer a dark grey base with one strong blue flash; others like a pale stone with gold or green. Look for a piece that pleases you from several angles, not just under the brightest light. Check the surface for cracks, chips or rough edges, especially if you plan to wear it. A little natural variation is normal.

Shape matters as much as colour. A flat cabochon or palm stone can show a broad flash, while a tumbled piece may flash only in one area. If you are buying jewellery, think about how the setting protects the stone. Labradorite is not fragile, but it has cleavage, so a sharp knock can cause a split. A bezel setting or a well-protected pendant is often a practical choice.

• Turn the stone in different lights
• Check edges and surface for damage
• Decide whether you want blue, gold or multi-colour flash
• For jewellery, consider a protective setting

Caring for Labradorite

Labradorite is reasonably durable for everyday handling, but it is not indestructible. With a Mohs hardness of about 6 to 6.5, it can be scratched by quartz, sapphire or diamond, and it can be damaged by a hard knock. Store it separately from harder stones, or wrap it in a soft pouch. Avoid dropping it onto hard surfaces.

Clean labradorite with lukewarm water and a soft cloth or very soft brush. Dry it afterwards. Avoid harsh household cleaners, prolonged soaking and sudden temperature changes. Ultrasonic and steam cleaners are best avoided unless a jeweller confirms the setting and stone are suitable. If your labradorite is set in jewellery, check the claws or bezel regularly and have loose stones tightened by a professional.

• Use lukewarm water and a soft cloth
• Avoid harsh chemicals and prolonged soaking
• Store away from harder stones
• Check jewellery settings regularly

Traditions and Symbolism

Labradorite has a rich place in story and symbol, though these are traditions rather than scientific claims. One story told in some Inuit traditions says that the Northern Lights were once trapped in the rocks of Labrador, and that labradorite holds some of that light. Other modern crystal-lore traditions associate it with protection, intuition and transformation, often describing it as a stone for times of change.

These meanings are cultural and personal. They can be a pleasant way to focus attention or mark an intention, but they are not evidence of physical effects. If you are drawn to labradorite for its colour, its story or simply because you like it, that is reason enough. You do not need to adopt any particular belief to enjoy the stone.

• Inuit tradition: a story of trapped Northern Lights
• Modern crystal lore: protection, intuition and change
• Treat symbolism as tradition, not fact
• Personal meaning is valid

Labradorite in Everyday Life

Labradorite works well as a pocket stone, a desk piece or a pendant because its flash is a small, changing pleasure. It is also a good stone for people who like a natural material with visible character. No two pieces are identical, and the same stone can look different on a grey day and in bright sun.

If you are new to crystals, start with a piece you can hold and turn. Ask questions about origin, treatment and care. A good shop will be happy to explain what it knows and honest about what it does not. At Peckham Crystals, we think the best relationship with any stone begins with clear information and a bit of curiosity.

Questions people ask

Is labradorite a crystal or a rock?

Labradorite is a mineral variety, specifically a plagioclase feldspar. It is often sold as a polished stone rather than a well-formed crystal, and the word crystal is used loosely in shops.

Why does my labradorite look dull sometimes?

The flash depends on angle and light. A piece can look grey from one direction and flash brightly from another; that is normal for labradorescence.

Can labradorite go in water?

Brief contact with lukewarm water is generally fine for cleaning, but avoid prolonged soaking and harsh chemicals. Dry it afterwards and take care with jewellery settings.
