This substantial 3.14 kg Casteel Mine chalcopyrite specimen features an extraordinary landscape of naturally iridescent chalcopyrite enveloped by sparkling drusy quartz. Rich copper-gold, magenta, violet, and bronze tones emerge throughout the specimen, dramatically contrasted by the pale, sugar-like quartz coating.
What sets this piece apart is its remarkable three-dimensional structure. Rounded and clustered mineral growths rise across the surface, many partially outlined in drusy quartz to create striking concentric and rosette-like formations. Open cavities extend into the specimen, revealing additional crystallization within and giving the piece exceptional depth and visual complexity.
Across the specimen, the balance between metallic chalcopyrite and fine quartz druse continually changes. Some areas display vivid exposed metallic color, while others are more heavily coated in sparkling quartz, creating a layered appearance that rewards close viewing from multiple angles.
At 3.14 kilograms, this is an impressive display specimen with substantial size, sculptural presence, and an unusually complex surface. Its combination of vivid natural tarnish, extensive drusy quartz, cavities, and densely clustered formations makes it a particularly striking example from the Casteel Mine in Missouri.
A dramatic and highly textural Casteel Mine specimen—selected for its size, color, intricate formation, and exceptional visual impact.
