⤱ Sulphur ⤱

Sulphur is a native element, formula S, that normally occurs as transparent or translucent yellow crystals. It occurs in areas of active volcanism, particularly around fumeroles or volcanic vents, and in orebodies as a result of the breakdown of sulphide minerals.

This specimen has a tiny but very bright crystal of sulphur sitting alonside brown pyromorphite in cavities in galena. It is from the Kintore Open Cut, Broken Hill, New South Wales.
