Bolo tie features a large piece of Leland Blue slag glass set in a handmade sterling silver setting. Leland blue slag glass is composed of slag from iron refining that occurred at the Leland Lake Superior Iron Company from 1870-1884 in the upper peninsula of Michigan. This slag was dumped into Lake Michigan at the close of the refining company, and still makes it's way to beaches along Lake Michigan. The reverse of the bolo tie is etched with a pattern that is an electron micrograph photograph of cast iron, to echo the origins of the Leland Blue stone. Tips are sterling silver and a dark brown braided cord forms the tie of the bolo tie. Bolo measures 2 inches long x 1 inch wide. Ties are 42 inches in length from tip to tip.
