Tucson, Arizona, USAThe zinc silicate Willemite forms multiple parallel stalactites of earthy deep carmine red to brownish brick red overgrown by delicate micro-acicular crystals of colourless to silvery white Willemite of the variety Troostite. Troostite is a manganese-bearing variety of Willemite. The earthy textured stalactites are likely a mixture of Willemite and Goethite with the longest of the group measuring 5 cm. The rich coating of Troostite in the form of fine acicular crystals gives a play of colours in shades of silver, grey and white due to transmitted light and the underlying dark stalactites. An unusual and fascinating miniature from Tsumeb with a M. Zinn Collection label.
