Sphere: LabradoriteDescription
Labradorite is a calcium-sodium plagioclase feldspar characterized by labradorescence, an optical phenomenon that can produce blue, green, yellow, and other iridescent colors when the material is viewed from particular angles. The effect results from light interacting with microscopic lamellar structures within the feldspar. Labradorite has a Mohs hardness of approximately 6–6½. This specimen has been cut and polished into a sphere.Create Date
