Specularite (Specular Hematite)
Hematite · Mineral Specimen / Decorative Stone
Crystal System
Trigonal; typically occurs in micaceous, foliated, or massive habits for this variety
Mineral Group
Oxides (Hematite group)
Chemical Formula
Fe2O3
Formation Process
Primarily formed through sedimentary precipitation or low-grade metamorphism of iron-rich sediments
About This Crystal
A sparkling, metallic gray to black variety of hematite composed of tiny, mirror-like flakes. It is opaque with a bright metallic luster and a granular, 'glittery' surface texture.
Physical Characteristics
Color: Steel-gray to black; Streak: Characteristic reddish-brown; Cleavage: None; Fracture: Uneven; Specific Gravity: 5.26; Luster: Metallic; Magnetic after heating.
Optical Properties
Opaque; highly reflective; shows no pleochroism or birefringence in this granular form; metallic glint from individual crystal faces.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), USA (Michigan/Arizona), South Africa, and Elba, Italy; found in banded iron formations
Hardness & Durability
Mohs hardness of 5.5 to 6.5; brittle; flaky habit makes it prone to shedding small glitter-like particles.
Care & Maintenance
Clean with a soft, dry brush; avoid ultrasonic cleaners or water as the micaceous flakes can trap moisture and shed; store separately to avoid scratching softer stones.
Rarity & Value
Common; valued for its aesthetic 'glitter' effect; price is generally low for raw specimens but increases for polished or jewelry-grade pieces.
Special Characteristics
Highly reflective micaceous flakes create a 'specular' or mirror-like reflection; non-fluorescent; leaves the diagnostic 'red' streak of hematite.
Lore & History
Historically used as a mirror due to its high reflectivity; traditionally associated with grounding, protection, and the root chakra in various cultural lore.
