Digenite crystals from Butte, MT, USA – miniature specimen as unique piece
This miniature specimen shows Digenite crystals from Butte, Montana, USA. The piece is characterized by its intense metallic luster with dark bluish to black areas and embedded golden shimmering sections.
The Digenite crystals form a compact, irregular surface with a strong metallic sheen. In places, small reflective crystal faces are visible, giving the specimen a lively sparkle. The color range includes deep blue, black and subtle violet tones, combined with contrasting golden inclusions, likely associated with Chalcopyrite or other copper sulfides. The crystalline character is clearly visible and creates a striking overall appearance.
