A sharp and complete-all-around crystal of magnetite from this famous quarry, which opened in 1887 and produced amazing specimens of magnetite and other rare minerals in its short lifetime. Today it is considered one of the most classic and desired USA localities. The Tilly Foster Mine was an iron mine in Putnam County, New York. This is as fine a thumbnail as you can ask for of a rare style and form of magnetite for any USA or thumbnail suite. It most likely dates to the WW1 era or before. From the award-winning thumbnail collection of Sharon and William Panczner, author of the book Minerals Of Mexico, and last seen and exhibited in the 1960s.
