A gorgeous blue translucent terminated prismatic crystal of tourmaline measuring 4.9 cm in length is set nicely upon a massive quartz matrix with other much smaller blue tourmalines. The strange color is due to copper. Measures 5.2 x 3.0 x 1.0 cm in size overall. No damage. Ref: MacDonald, D.J. and Hawthorne, F.C. (1995) Cu-bearing tourmaline from ParaĆ­ba, Brazil. Acta Crystallographica C51, 555-557.
