Låvenite - Sold

Låvenite is a complex zirconium silicate, and a member of the wöhlerite group. Brögger (1884) named the mineral for its type locality, Låven Island in Norway.

Låvenite here forms radiating brown crystals to 10 mm in a crystalline rock consisting of cancrinite, orthoclase, and magnesio-arfvedsonite. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
