Labradorite is a type of feldspar mineral that is known for its iridescent play of colors, which can range from blue to green, yellow, orange, and red. The colors are caused by the way light interacts with the mineral’s internal structure, which is made up of thin layers of different minerals.
What Causes the Color of Labradorite?
The color of labradorite is caused by a phenomenon called labradorescence. This is a type of optical interference that occurs when light waves interact with the mineral’s internal structure. The thin layers of different minerals in labradorite act as a diffraction grating, which causes the light waves to be scattered and reflected in different directions. This scattering of light produces the iridescent play of colors that is characteristic of labradorite.
The color of labradorite can vary depending on the angle at which the light strikes the mineral. This is because the diffraction grating effect is strongest when the light is perpendicular to the layers of minerals in the labradorite.
