Description
Geological & Mineralogical Overview
This Crocoite specimen from Tasmania exhibits vibrant red-orange, elongated crystals of lead chromate (PbCrO₄) on a contrasting matrix. Each crystal displays exceptional translucence and luster, characteristic of the world-renowned Dundas deposits, which have produced the most celebrated crocoite specimens ever found.
Crocoite forms in the oxidized zones of lead ore deposits, where chromium-rich fluids react with galena-bearing host rock. The process yields striking prismatic crystals that grow in radiating clusters—delicate yet visually captivating.

History & Collector Significance
Crocoite was first identified in Russia in 1766, but it was the discovery of the Dundas, Tasmania deposits in the late 19th century that brought it global fame. The Tasmanian crystals remain unmatched in color saturation and crystal size. Collectors prize them for their fiery brilliance and geological purity. Crocoite also played a notable role in early chromium pigment development, marking it as both scientifically and aesthetically important.
