This specimen provides a great opportunity to acquire an exceptionally rare species from a world-famous yet seldom seen locality, the Rio Tinto mine in Andalusia, Spain.  This excellent crystallised specimen of the lead-arsenic sulphosalt Gratonite is ex-matrix and a complete mixture of perfect, sharply defined Gratonite crystals intermixed with granular Gratonite.  The trigonal crystals attain at least 5 mm tall and line the vuggy interior and external faces of this highly porous small miniature (or large thumbnail).  The Gratonite is a sooty dark grey to black with a dull to metallic lustre.  It is great to see a specimen from the Rio Tinto mines, a locality I visited over forty years ago and have fond memories of.  This rare sulphosalt is from the Dr Josef Clemente Collection of southern Germany and comes with a ‘Museo Mineralogico of Madrid’ label.
