This is a highly important specimen for what it is, not just for the massive amount of crystallized silver present but also for the locale. Silver Islet is a famous old location mined circa early 1900s. It is now closed and gone forever. It was one of those funny stories in mining that you hear about and cannot believe - they actually mined this silver from an islet in the Great Lakes, while pumping water out from behind barricades. Verifiable Silver Islet specimens are few and far between. This is typical of the style and matrix association, and comes from the private silver species collection of a dealer known to specialize in such pieces, and verified by Rod Tyson (an expert on such). However, one seldom sees anything beyond small pieces from here. This monster, at 455 grams and complete all around as a display quality specimen, is truly significant. Comes with custom lucite display base. Ex. Charles Leavitt Collection (well known for a large and diverse silver suite).
