Petoskey Stone and Leland Bluestone Two Stone Pendant set in Sterling Silver, Hand Crafted, One of a Kind, 39.7 x 28.5mm. This is a one of a kind (ooak) art piece. I personally hand cut the cabochons,then hand forged the metalwork to take advantage of the beauty of these gemstones.
Petoskey Stones can be found on various beaches in Northern Michigan with many of the most popular being those surrounding Petoskey and Charlevoix. Similar fossil corals occur in a variety of locations, however the name Petoskey stone should only be applied to those from Northern Michigan.
Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized coral, Hexagonaria percarinata. The stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern portion of Michigan's lower peninsula.
From 1870 to 1885, Leland, Michigan was a smog-filled industrial town, the main industry was conducted by the Leland Lake Superior Iron Company. The smelting industry failed due to large overhead costs and the lack of a good harbor in Leland, the remains of the industry, including heaps of slag, were dumped into the harbor. Slag is a byproduct of the smelting process: raw ore is heated, and the desired iron ore is separated from various natural impurities. When those impurities cool, the result is stone-like slag. Leland Blue is the mixture of blue glass with other chemicals — but the varying chemicals can also cause the slag to appear purple, gray, or a shade of green. Today, people find this slag material on the shores of Leland’s beaches.
