Item Description
A rarely seen matrix specimen of Dravite Tourmaline from the Pedra Preta Pit in Brumado, Brazil. For reference, this area is one of the world's largest Magnesite deposits. This piece is filled with rather lustrous, sharp, well-formed, trigonal crystals of a rich orange-brown hue, with minor associated white/colorless Magnesite on a dark blue colored matrix. The largest Dravite measures 1.5 cm There is some visible damage, so the piece is not pristine, but it's a really cool and unusual example of an uncommon Tourmaline species from a classic locality. Please note that these are confirmed Dravite, and not Fluor-uvite or Uvite. From the collection of Rolando Gioia (a contributor to definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
