Pyromorphite (lead chloro-phosphate) was a common mineral of the oxidised zone of the Broken Hill orebody, and exceptional specimens of various crystal forms and colours were found. Some examples were yellow and some brown, while others were green. Their crystal habits varied from almost needle-like to thick barrels. This example illustrates one of those forms – large, barrel-shaped, six-sided, clove-brown crystals bristling all over the specimen.
