Bournonite on Siderite
stock #8.1-447
Canutillos
Potosi,
Bolivia
7.3 x 6 CM (cabinet)
price: $150
A very good combination piece consisting of 2 intersecting cogswheels of Bournonite surrounded by sharp Siderites with a flattened Rhomb habit. The underlying matrix is nearly pure pyrite. The Bournonites are damage free with a gunmetal luster and reach 1.8 CM. I mave not seen good specimens of this combination for years, this would be a good addition to a sulphide suite or Bolivian collection.
