Norway’s classic locality for anatase is undoubtedly Matskorhae in the Hardangervidda National Park, near Ullensvang, Hordaland, which has produced lustrous, pointed, blue-black tetragonal bipyramids to several cm…though most are under 1 cm…artfully scattered on clear quartz crystals. A more recent locality is that in the Valdres region, which produces crystals that are, at first glance, somewhat similar to those of Hardangervidda. Two notable differences in the Valdres specimens are the prominent, flat basal terminations on the bipyramids and a pronounced red undertone, though basically the same color as Hardangervidda crystals. As well, the matrix, where present, is commonly drusy albite. Crystals are typically loose singles to 2.5 cm long, but bright and handsome parallel groupings also occur.
