Bornite, Pyrite & Quartz (Trimingham Coll.)

Item Description

A showy and excellent combination from this classic locale. Sharp, sooty charcoal-gray, bornite crystals to 1.5 cm are aesthetically clustered with highly lustrous, striated, brassy pyrite pyritohedrons and quartz points on the massive pyrite matrix. The bornites are in good shape. Bruising and periphery wear are noted, but this remains a highly representative older combination example from the famous Steward Mine. Ex Bob Trimingham Collection and previously in the Lanny and Steve Thompson Collection of Livermore, CA.
