Description
This listing is for a 100% genuine Anhydrite Crystal from Cumbria, United Kingdom. You will receive the exact specimen shown in the photographs. The piece was carefully selected for its clarity, structure, and geological significance. A scale cube = 1cm is shown for accurate size reference.
Anhydrite (CaSO4) is a mineral closely related to gypsum but without water in its structure. It often forms in evaporite deposits where seas have dried up, leaving behind beds of crystalline minerals. Anhydrite is relatively rare in display-quality form from the UK, making this a prized piece for collectors.
All of our Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity.
Key Features:
- Species: Anhydrite
- Chemical Formula: CaSO4 (Calcium Sulfate)
- Crystal System: Orthorhombic
- Habit: Massive, fibrous, tabular
- Colour: Pale blue, grey, white, or colourless (depending on impurities)
- Lustre: Vitreous to pearly
- Hardness: 3–3.5 Mohs
- Cleavage: Perfect in three directions
- Fracture: Uneven
- Streak: White
Geological Context:
- Locality: Cumbria, UK
- Depositional Environment: Typically forms in marine evaporite basins
- Geological Stage: Most anhydrite in the UK is associated with Permian to Triassic age sedimentary formations
- Morphology Features: Tabular or fibrous habit with blocky cleavage faces
- Notable: Transforms to gypsum (CaSO4·2H2O) in the presence of water, and thus is less stable at surface conditions
Taxonomic Notes:
- Order: Sulfates
- Family/Super Family: Anhydrite Group / Not further subdivided
- Formal Identification: First described by Abraham Gottlob Werner in 1804. The name “Anhydrite” comes from the Greek anhydros, meaning “without water.”
This rare Cumbria-sourced Anhydrite is a unique addition to any geological collection and is also appreciated for its calming and stabilizing properties in metaphysical circles.
