Item Description
Wurtzite is a relatively uncommon zinc, iron sulfide. It usually occurs as massive ore or as banded, botryoidal crusts. It is very rare as displayed in the sharp, hexagonal, stacked, tabular crystals on this superb thumbnail from the Howard Belsky Collection. The lustrous crystals have a nice purple and magenta iridescence to them. This classic, old-time specimen, dating to the 1960s or 1970s, is from the famed Siglo XX Mine of Bolivia.
