Molybdenite, Boss Mountain Mine, Williams Lake, British Columbia, Canada (Ex Prosper J. Williams)

A well-defined molybdenite crystal in quartz matrix. Excellent contrast between the two species. Showy specimen for the size. Very difficult to find these days with this piece coming from the old inventory of Prosper J. Williams, likely from the late 1970s-early 1980s. Accompanied by one of Prosper's labels. From Boss Mountain Mine, near Williams Lake, BC. Dimensions: 3 x 5 cm. SOLD
