Titanite (''floater'' twin) included with ''Chlorite'' (ex Al Kidwell Collection)

Item Description

A cool old-time Swiss Titanite (Sphene) specimen from the Gletsch area of the Furka Pass. This piece is a sharp, lustrous twin comprising thin bladed crystals of Titanite which are included with greenish-grey "Chlorite" (likely Clinochlore). The piece is a complete "floater" with no point of attachment. If you collect Alpine minerals, I'll bet you don't have a Titanite from this locality in your collection. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974. The label accompanying the piece dates it back to 1960 with the name H. Adrian written on the back.
