About the Stone
Labradorite looks like dull grey stone until it is turned, when a flat sheet of blue, teal or gold lifts off the surface and then vanishes. That flash comes from light interference inside extremely thin alternating layers within the stone, which is why it appears at one angle and not another. Cutting decides how much of it you see, so no two strands flash in the same places.
- Family
Feldspar group (plagioclase)
- Hardness
6 - 6.5
- Note
That flash - labradorescence - is interference, not pigment. The stone separated as it cooled into extremely thin alternating lamellae of two feldspar compositions, and light reflecting off those internal layers interferes with itself, returning one narrow band of colour at one particular viewing angle.
