Rare Chalcanthite Mineral Specimen
Description
This chalcanthite specimen features broad, layered blue crystal growth spread across its natural matrix, creating a textured surface that is both dense and dynamic. The crystals rise in uneven terraces, with fibrous blades interlocking and overlapping as they extend outward. The intense blue coloration remains consistent throughout the piece, balanced by the earthy tones of the host rock beneath it.
Unlike most Chalcanthite, this specimen contains a dense thick growth of crystal blades, making it especially unique.
Dimensions & Weight
Dimensions: 2.75” x 2” x 1.75”
Weight: 141g
Collector’s Notes
Natural chalcanthite is increasingly difficult to source, due to its fragile and water soluble nature. Specimens from the Planet Mine are especially sought after due to the locality’s history and the quality of crystal growth found there.
Unlike laboratory-grown examples, this specimen shows organic growth patterns, unique crystal development, and subtle variations that speak to its natural origin. .
This piece shows natural variation in crystal length and density, a clear indicator of authentic formation rather than laboratory growth.
Care & Handling
Chalcanthite is water-soluble and sensitive to humidity. This specimen should be kept in a dry environment, away from vents, and handled minimally. It is best suited for display in a controlled collection rather than frequent handling.
Highlights
Natural chalcanthite
Famous Planet Mine, Arizona locality
Vivid, saturated blue coloration
Dramatic bladed and fibrous crystal habit
Rare Specimen
Mineralogy
Chalcanthite is a hydrated copper sulfate mineral that forms in arid environments, often as a secondary mineral in copper deposits. Its intense blue color comes directly from its copper content. Due to its water solubility, chalcanthite forms under very specific conditions and is rarely preserved long-term in nature, making intact specimens particularly uncommon.
