Physical properties

Hardness: 5.5-6.5; Color: Steel-gray to black with metallic sparkles; Luster: Specular/Metallic; Crystal Structure: Trigonal; Gravity: 5.26.

Formation & geological history

Formed through hydrothermal processes or metamorphism of iron-rich sedimentary rocks. This variety is often found in schists created under high-pressure metamorphic environments.

Uses & applications

Primary ore of iron. Used in pigments (ochre), jewelry (beads), and as a decorative collector mineral due to its sparkle.

Geological facts

Specularite gets its name from its mirror-like reflections. It is the same chemical composition as common rust, but in a highly crystalline form.

Field identification & locations

Identify by its characteristic sparkling 'glitter' effect and red-brown streak when rubbed on unglazed porcelain. Commonly found in major iron ranges like those in Michigan, Brazil, and Australia.
