I found on MINDAT that Schipsius is an antiquated name used by Kenngott in 1866. It was located southeast of the St Gotthard pass.This was a unique, famous find of the time, I am told. I think you could say that, pedigree aside, this is one of the more dramatic byssolite-included quartzes imagineable out there?! The piece shows an incredible spray of beautiful byssolite needles within. Sadly, there is a big shallow slice out of the left side of the termination for 2 cm down from the tip - not easily visible in pics, but it is there and hence the low value (otherwise, more like 10x this price). Still, its an important survivor from an apparently well known find of the 1800s, I am told - though a rare one, I admit. Note an inked black arrow on the back of this specimen was made by the early-1900s AMNH curator Gratacap in curating the display specimens from the Bement collection after it was donated to the AMNH by financier JP Morgan, who purchased the collection after Bement's death. The arrow denotes the rear direction on the shelf on which the specimen was to be placed, thus showing its proper orientation on the display shelves of the museum. As the MinRecord archive states, Clarence Sweet Bement was one of the greatest mineral collectors of all time, from around 1866 to 1900 known for his high level of taste in specimens - even in the oddities, rarities, and classics. The man had, be they rare or pretty or ugly or common, the best of the era. If he could live with the damage, given the importance of the find and its display quality, so can I (at the right price).
