ID: CC21513
Prenteg is famous for the occurrence of the trimorphous minerals Anatase, Brookite and Rutile, each a different morphology of titanium dioxide. Prenteg is the type locality for Brookite.  Alpine cleft mineralisation occurs throughout this region of Wales and this lovely miniature is a fine example.  The top surface of a slightly chloritized granitic matrix is covered with crystals of Quartz, Albite and Calcite and towards one end sit two well-formed Anatase crystals, the larger measuring 3 mm across.  Each Anatase crystal forms a four sided striated pyramid of translucent clove brown.  This choice specimen comes with a Richard W. Barstow Collection white label.
