Anatase from Pakistan, Balochistan, Kharan District, Ras Koh Mountains

Multiple sharp, shiny, black anatase crystals, partly oxidized, thus with blueish iridescence, on matrix covered in quartz crystals. The largest back crystal of 13 mm size is penetrated and surrounded by quartz crystals. The very lustrous crystal is not only iridescent because of an oxide coating but is also translucent which makes it very blue in addition to the contrasting metallic gray.
