A classic and old-time sperrylite specimen from the historic Type Locality - the Vermilion Mine at Sudbury, Ontario. This is a rare platinum-containing species. This specimen has a (large for this locality) 4 mm, sharp, splendent sperrylite crystal set atop iridescent chalcopyrite-rich matrix. Excellent, highly representative material from a famous mine and locality. But in superb quality - the eye visible crystal is mirror bright. Sperrylite was discovered in 1889. This is undoubtedly old material probably from the late 1800s, as it has an old label on the back of the specimen.
