Titanite var. Sphene
4.8 x 4.2 x 2.8 CM (miniature)
A choice cluster of old time Sphene crystals with a small bit of matrix. In person these are quite gemmy, very transparent and have fantastic growth structures on several faces. In fine condition there is one small chip on a crystal edge that is the logical base of the specimen and not visible on display.
Ex Commercial Mineral Corp (a NYC based dealer) The label for this dates after 1956 though the vintage is likely mid sixties. Ex Charles M. Noll and Jimmie Dufoe collections as well. Presents well from several angles, best appreciated in person.
A transparent, glassy single crystal of Kyanite on a small matrix of Quartz. Perfect, complete and very lustrous, this slender crystal comes from a well known Pegmatite and is in remarkable, undamaged condition. With even a weak backlight this glows a rich blue and looks fine from any angle. Kyanite is not a rare mineral but this quality is very uncommon and the proportions are very elegant.
Titanite v. Sphene
5.6 x 5.5 x 5.1 CM (cabinet)
A sharp and "monumental" looking cluster of Titanite in crystals to 3.1 CM. Transparent and with a good green color, some faces are smooth and glass clear and others have micro steps and a more etched look. Unknown inclusions add a little red zoning in a few spots. In very good condition for the specie, esthetic.
