Mineralpedia Details for Caledonite
Named after the ancient Latin/Roman term for the Highlands of Scotland, Caledonia, which is where the first known locality lies at the Leadhills in Strathclyde (Lanarkshire). Caledonite is an uncommon mineral that occurs as a secondary mineral in oxidized copper-lead deposits. Additional localities for Caledonite include in England, Russia, Iran, the United States, Chile, Australia, and several others. Associated minerals include cerussite, anglesite, leadhillite, brochantite, linarite, azurite, and malachite. Caledonite is piezoelectric and generates a charge in response to pressure.

Caledonite from Rožná dep., Vysočina, Moravia, Czech Republic
Caledonite from Reward mine, Inyo Co., California, United States
Aqua-blue, lustrous, well-formed crystals of Caledonite to 1mm associated with 0.5mm waxy looking Chlorargyrite crystals.
Caledonite from Anarak dist., Esfahan, Iran
Lustrous blue, striated crystals to 1mm throughout matrix with perhaps darker blue Linarite or Diaboleite. Not too many minerals on the market from Iran.
Caledonite from Brown Monster mine, Inyo Co., California, United States
A single, gorgeous 2mm striated Caledonited crystal in predominately Leadhillite matrix. The Leadhillite is mostly massive, but can be seen in the photos only as light-reflected plates. Also in association is yelow Oxyplumboromeite.
Caledonite from Mammoth mine, Tiger, Pinal Co., Arizona, United States
The specimen is all Caledonite with an aggregate of numerous prismatic Caledonite crystals to 6mm. A great piece for those of you who collect Tiger minerals.
