Chalcanthite Rare Mineral Specimen
Description
This chalcanthite specimen features a concentrated pocket of vivid blue crystal growth partially enclosed by its natural host rock. The crystals emerge from within the matrix rather than sitting openly on top, giving the piece a sheltered, almost hidden quality. The saturated blue tones contrast sharply with the surrounding stone, drawing the eye inward toward the crystal growth rather than outward across the surface.
Dimensions & Weight
Dimensions: 2.5” x 2” x 1.75”
Weight: 57g
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.
