6.1" Tall, Flashy Polished Free Form Labradorite
The labradorescence is not caused by the colors being reflected on the surface of the specimen. Instead, light enters the stone, hits a twinning surface within the stone, and reflects from it. The color seen is the color of light reflected from that twinning surface. Different twinning surfaces within the stone reflect different colors of light. Light reflecting from different twinning surfaces in various parts of the stone can give the stone a multi-colored appearance.
Labradorite is named after where it was first found in Labrador, Canada. Today, the most prolific deposits and the source of most commercially available labradorite occur in Madagascar and Russia.
