Bill & Carol Smith Collection Bill and Carol Smith collected sulfosalts in general, but they collected bournonite as an impressive stand-alone suite with representation from many disparate localities.

Here is another exceptional Chinese bournonite. This is a large floater single tabular crystal with excellent luster. The uneven edges suggest that the crystal is likely a twin, but I can’t be certain. The attached quartz crystal doesn’t show as Bill and Carol displayed the specimen, but it could just as easily be displayed in the opposite direction.
