A number of prismatic crystals and crystal sections of light blue-green to white Leadhillite measuring to 8 mm are scattered over the top of this rich miniature from the Mammoth-Saint Antony mine at Tiger in Arizona. Leadhillite is a lead sulphate carbonate hydroxide and is associated on this vuggy matrix with Willemite crystals and sparse colourless cubic crystals of Fluorite. It is accompanied with a Bideaux Minerals of Tucson, Arizona label.
