This leland slag piece was a lot of fun to set. With its irregular white “flecks” and “bubbles”, I was able to continue the pattern onto the silver setting using texture and oxidization.


This unique “gem” is a byproduct of the short-lived days of smelting iron ore in Northwest Lower Michigan. The ore from the Upper Peninsula’s Mesabi iron range arrived in Leelanau Co. by schooner. A charcoal made from beech and maple hardwoods plus a local limestone flux were used to refine the ore; the slag byproduct was considered waste and dumped into Lake Michigan. This material ranges in color from black to green, to blue and purple, with the various shades of water-like blues being the most prized and rare. Under 2% of the slag created was blue, depending on environmental factors. The lucky and determined beachcomber may still find pebbles along the shore.
