MD-199680 - Antigorite - - Archived Jackson Co., North Carolina, USA small cabinet, 9.1 x 5.6 x 4.9 cm.
9.1 x 5.6 x 4.9 cm. A vein of massive yellow genthite, a Kaolinite-Serpentine group mineral related to chrysotile, in sandstone. From the noted collection of William Drown who, according to the Mineralogical Record Archive on him, was an umbrella manufacturer who used his fortune to amass a collection of some 6000 mineral specimens. His collection was kept by his family for a generation after his death and then donated in 1918. Ex. Philadelphia Academy of Sciences Collection.
MD-204046 - Antigorite - - Archived Wood's Chrome Mine (Wood's Mine), Texas, Little Britain Township, Lancaster Co., Pennsylvania, USA miniature, 4.6 x 3.9 x 1.9 cm.
4.6 x 3.9 x 1.9 cm. Genthite is an old synonym for antigorite. The bright green, lustrous antigorite richly covering this specimen has an unusual knobby/bubbly/drusy form.
MD-225235 - Antigorite - - Archived Tilly Foster mine, Brewster, Putnam Co., New York, USA small cabinet, 6.8 x 4.4 x 2.7 cm.
6.8 x 4.4 x 2.7 cm. This is a surprisingly attractive specimen of a rare serpentine group species called Antigorite, from the old Tilly Foster Mine. According to MINDAT: Large iron ore (magnetite) deposit discovered in 1810. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. Usually, you get chondrodite and a few other species like clinochlore as mere associations. However, here it is definitely not common to get a good specimen of one of the rock-formers like this serpentine group species that is actually a "specimen" and not a "rock". This is a really interesting, showy, crystallized piece, with a distinct curvature to the crystals and to the specimen overall. Ex. Ken Hollman Collection.
USA-77 - Antigorite - AUS$ 442 SOLD Tilly Foster Iron Mine, Putnam Co., New York small cabinet, 6.8 x 4.4 x 2.7 cm ex. Ken Hollman
This is a surprisingly attractive specimen of a rare serpentine group species called Antigorite, from the old Tilly Foster Mine. According to MINDAT: Large iron ore (magnetite) deposit discovered in 1810. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. Specimens today are obviously hard to come by, and I know people who are dedicated to collecting Tilly material. Usually, you get chondrodite, and a few other species like clinochlore as mere associations. However, here it is definitely not common to get a good specimen of one of the rock-formers like this serpentine group species, that is actualy a "specimen" and not a "rock" . This is a really interesting, showy, crystallized piece, with a distinct curvature to the crystals and to the specimen overall. ex.
