This is a beautiful lot of Leland Blue Stones which are 150 year old slag glass from the iron smelting industry. These pieces look glassy dull blue or gray but most can be polished or sanded to bring out a nice shine. Due to the action of the waves these specimens almost look like beach glass.

In the 1800s iron furnaces were often set up along the shores of the Great Lakes in Michigan. During the smelting process in a huge furnace, raw iron ore was super heated to remove any natural impurities. When the impurities cooled, they produced a glass like slag. The slag was shipped out and dumped into the harbor as a waste product. These samples were gathered from the shoreline and were naturally tumbled and washed by the waves.

The colors of Leland Blue stone vary between different shades of blue, green, gray, purple and sometimes white.

Leland Blue Stone is a generic term often used to describe the slag from any one of the furnaces around the Great Lakes of Michigan. Although the finest blue color comes from Leland Michigan. Another popular color is Frankfort Green from Frankfort Michigan.

Leland Blue Stones are sought after by collectors and jewelry makers alike because of their relative rarity. Since these stones can only be found around the Great Lakes of Michigan it makes them quite unique and special around the World.

Rock hounders, collectors and jewelry makers scour the beach to find pieces of Leland Blue Stone washed up by the waves.

You can polish these by hand or in a rock tumbler. You can cut them and shape them for jewelry. Or you can put them on display as is. A light shining behind these pieces often brings out their beauty.
