Description

Yellow and orange-yellow legrandite crystals on a chalcocite-rich sulphide matrix; tiny white needles of adamite are present in cavities in the chalcocite but are not discernible in the photograph (Exhibit1). The legrandite crystals are locally quite gemmy and terminated prismatic crystals are present in a cavity in the main mass of legrandite.

Mark Feinglos acquired this specimen from Bill Pinch in November 1991. Pinch had purchased it (and several other specimens from the so-called "Zinc Pocket") from Charlie Key, who bought most of the specimens from this pocket during a late 1991 visit to Tsumeb (Southwood 2022d).

Feinglos' data card (exhibits 2 and 3) records the information, presumably from Key, that the specimen was collected in August 1991.
