Kingston, Ungrouped

Kingston is a unique iron meteorite, without any close chemical relatives.  It appears to be a magmatic iron, and may be the only fragment we have from its parent body’s core.

From Buchwald:

Foote advertised slices of Kingston in the company’s 1912 catalogue:

This 8.9 gram slice from the Philadelphia Academy of Sciences has managed to stay with its original glass-fronted box and Foote label for over a century.  Thanks to Anne Black for making this specimen available.
