Caledonite (ex Roots)


Caledonite is a copper lead sulfate, first noted in Scotland. Professor François Sulpice Beudant (1787-1850) named the mineral in his 1832 Traité Élémentaire de Minéralogie using the Roman name of Scotland, Caledonia.

This specimen of caledonite comes from the defunct Tiger mining camp, a prolific mineral specimen producer during the 1930s to 1950s. Tiger is generally considered to be the source of the most beautiful caledonite specimens. Caledonite crystals here reach 2 mm forming a pocket on a matrix of altered sulfides and white leadhillite. Tiger caledonite specimens are difficult to find! This specimen was part of the Charles Trantham (1936-2020) estate. A Bob Roots (1891-1971) label accompanies this piece.
