Labradorescence, explained for first buyers

Choosing Labradorite: How to Read the Flash

In short: When choosing labradorite, judge the flash on four points: its colour, with green, gold, orange and purple rarer than blue; coverage across the face; intensity in ordinary room light; and direction, ideally visible face-up. Dark grey body lines are normal, but visible cracks lower the price. Check the side for a doublet's join line.

Reviewed on

Labradorite is a feldspar that can look plain grey one moment and burst into peacock blue, green, gold or orange the next. That play of colour, called labradorescence, is what you are paying for, and it behaves differently from the sparkle of most gems. A first-time buyer who understands how it works can choose a stone confidently from photographs and video.

What labradorescence is

Inside labradorite are extremely thin alternating layers that interfere with light, much as a film of oil on water creates colour. The effect only appears at certain angles, so a stone can look dark until it is tilted the right way. This is normal, not a defect.

Four things to judge

1. Flash colour

Blue is the most common. Green, gold, orange and especially purple or a full spectrum of colours are rarer and generally command more. Very fine full-spectrum material is sometimes called spectrolite.

2. Coverage

How much of the face lights up? A stone that flashes across most of its surface is worth more than one with a small patch of colour.

3. Intensity

Strong, saturated flash that is visible in ordinary room light beats a faint shimmer that needs a spotlight.

4. Direction

Ideally the flash appears when the stone is viewed face-up, which is how you will see it on your hand. A well-oriented cut matters, so ask for a video or a photograph from the front.

Body and clarity

Most labradorite has a dark grey body with natural lines and needle-like inclusions; that is expected. Rarer clearer material exists. Visible cracks, especially across a ring stone, should lower the price.

Coated stones and doublets

  • Coated quartz or glass: shows an oily rainbow over the whole surface from every angle, rather than flash that switches on and off with direction.
  • Doublets: a thin slice glued to a backing. Look at the side for a join line.

Ask the seller in writing whether the stone is natural and solid.

Cleavage, knocks and cleaning

At 6 to 6.5 on the Mohs scale labradorite is moderately hard, with cleavage planes that make it sensitive to knocks. It is ideal for pendants and earrings, and fine in a ring worn with some care. Clean with mild soap and water; avoid ultrasonic cleaners.

A modern crystal-lore stone

Labradorite belongs to modern crystal lore rather than classical astrology and is worn for imagination and protection. These are beliefs, not promised effects; for planetary stones see our rashi guide.

Common questions

Something else on your mind? Ask us directly — we answer on WhatsApp during working hours.

Why does my labradorite look grey sometimes?

Its colour flash only appears at certain angles. Tilt the stone under a light and the colour will switch on.

Which labradorite colours are rarest?

Blue is the most common. Gold, orange, purple and full-spectrum flash are rarer and usually cost more.

How can I tell coated quartz from labradorite?

A coating shows a rainbow over the whole surface from every angle, while labradorite's flash appears and disappears with direction.

Is labradorite suitable for a ring?

Yes, with care. It is moderately hard with cleavage planes, so protective settings are best.
