Detailed Description

This is a group of good-sized interlocking pseudo-hexagonal strontianite crystals. The crystal group is all-strontianite with no matrix – it looks like it might have formed as a floater, with minor magnesite on a couple of surfaces. These crystals exhibit cyclic twinning and some minor golden yellow core zoning. In excellent condition, no damage as displayed. Amazing crystals for the species.

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.
