Specularite is a variety of hematite characterized by its shiny, reflective surfaces, often resembling polished metal. It typically forms as tabular or platy crystals and occurs in metallic-gray to black colors. Specularite derives its name from the Latin word "speculum," meaning mirror, due to its reflective nature. The mineral is primarily composed of iron oxide and often occurs in association with other iron-bearing minerals in metamorphic and hydrothermal environments. Specularite has been used historically as a decorative stone and pigment, and it holds significance in both industrial and lapidary applications. Its distinct luster and metallic appearance make it a valued specimen among mineral collectors and enthusiasts.
