unusual facts about Labradorite


Labradorite

This labradorescence, or schiller effect, is the result of light diffraction within the lamellar intergrowths – fine, adjacent layers of the separate materials (lamellae) comprising the whole rock phase – created when conditions do not allow for sufficient diffusion to the materials' equilibrium composition.
