A sharp, mirror-bright, dipyramidal crystal of dark Anatase measuring 15 x 6 x 6 mm with gemmy bluish flashes of color, is perched on glassy Quartz heavily included with brownish, fuzzy-looking clay(?). A portion of the Anatase is matrix contacted. This was collected by Ed Swoboda from a small prospect that Ed labeled as Lavrinha, near Cuiaba, Brazil. It was held back by Ed Swoboda for nearly 20 years, when I purchased it in the early 1990s for my personal collection. These pieces are very rare.
