ID: CC15780
The 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.
