Chabazite with Offretite (classic material) (ex Francesco Bedogne Collection)

Item Description

A beautiful specimen of the well-known, but hard to find Chabazites from the locality at Arno Lake (Lago d'Arno) in Lombardia. Sharp, very well-formed, rather lustrous, white pseudo rhombic (triclinic) crystals of Chabazite (possibly Chabazite-(Ca)) with micro prismatic groups of the rare zeolite species, Offretite. The Offretites are confirmed from this locality, as they are often hard to distinguish from Erionite. From the worldwide collection of famed Italian mineral collector, field collector and author, Francesco Bedogne of Sondrio, Italy (Collection #1926). Bedogne wrote dozens of articles and several books about the mineralogy of Italian Alpine localities such as Val Bregaglia, Val Masino, Val Codera, Val Spluga, Valtellina and the famous Val Malenco. He was also the founder of the Valtellinese Mineralogical Institute.
