Specularite (Hematite)
Hematite var. Specularite · Mineral Specimen / Decorative Stone
Crystal System
Trigonal symmetry; displays micaceous, platy, or foliated crystal habits in Specularite varieties.
Mineral Group
Oxides (Hematite group)
Chemical Formula
Fe2O3
Formation Process
Primarily formed through sedimentary precipitation in banded iron formations, or via hydrothermal and metamorphic processes.
About This Crystal
An opaque mineral with a bright, mirror-like metallic luster. It appears as a cluster of sparkling, flat, plate-like crystals often referred to as 'micaceous hematite.' The color is steel-gray to black, frequently appearing on a brownish-red earthy matrix.
Physical Characteristics
Color: Steel-gray; Streak: Cherry red to reddish-brown; Cleavage: None (parting may occur); Fracture: Uneven; Specific Gravity: 5.26; Luster: Metallic; Sensation: High density (heavy for its size).
Optical Properties
Opaque; displays high metallic reflectivity. Non-pleochroic and singly refractive due to opacity.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), USA (Michigan/Arizona), Morocco, and South Africa.
Hardness & Durability
Mohs hardness: 5.5 - 6.5. It is relatively brittle and the thin plates can flake off easily, making it fragile for jewelry.
Care & Maintenance
Clean with a dry, soft cloth or warm soapy water; avoid ultrasonic cleaners which can shatter the plates. Store separately to prevent scratching other stones.
Rarity & Value
Common; valued by collectors for high-luster 'specular' flash. Generally inexpensive, with value determined by the size and brilliance of the crystal faces.
Special Characteristics
Specularite is defined by its sparkling, 'glitter' effect caused by the reflection of light off thousands of tiny mirror-like crystal faces.
Lore & History
Historically used as a pigment (ochre) and for early mirrors. In lore, it is considered a grounding stone associated with the root chakra and protection.
