This specimen is crowned with exceptional sharp, pseudo-hexagonal plate-like crystals of strontianite. These crystals show cyclic twinning, but most of the pseudo-hexagonal strontianite crystals from this locality form tall stacked crystals or crystal aggregates – this form of platy crystals is very uncommon. In excellent condition – no damage. This is a beautiful strontianite.
About these Strontianites
These strontianites are from the collection of Franz Lammer (1914-1997), and were collected during the period approximately 1967-1992. Although strontianite is a relatively common mineral, it is difficult to obtain fine collection specimens of sharp crystals. Among the finest ever found are the specimens that came from the magnesite deposit at Oberdorf an der Laming, Styria, Austria, a locality that has produced superb crystals of a few different habits.
