Leland Blue cut into the shapes of our Upper & lower Michigan. It is on a stainless steel chain that is 18″. The upper and lower measure about 2 1/4″ x 1 3/4″. Leland Blue is from Leland MI, a glass slag, by product from the pig iron factories. It was dumped along the shore to hold back erosion. It comes in many colors of blues and purples plus we get black Leland Blue once in awhile.
