About the Stone
Labradorescence is an interference effect: the stone cooled into very thin alternating internal layers, and light bouncing between them returns a narrow band of blue, teal or gold at one specific viewing angle. Orientation during cutting therefore decides everything about the flash. One earring may show blue and its pair a greener tone, from the same block.
- 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.
