Bixbyite

Rob Lavinsky

The Arkenstone

  

The specimen consists primarily of phlogopite with cubic crystals of bixbyite with semi metallic luster. The largest crystal is 2 mm across. This specimen was Flink's #335 in his collection and was identified by Mason (whose name appears on von Eckermann's label) in 1942. Bixbyite is known from only a few specimens from Långban. It is considered a very rare species from this locality.
