LabradoriteDescription
Labradorite is a calcium-sodium plagioclase feldspar intermediate in composition within the albite-anorthite series. It is particularly associated with labradorescence, an iridescent optical effect produced by light interacting with microscopic lamellar structures within the feldspar. Labradorite has a Mohs hardness of approximately 6–6½. This specimen preserves a natural or minimally worked form displaying blue iridescence.
