    The Lake Superior agate is a form of agate that has been tarnished by iron and is found on Lake Superior's shoreline. The gemstone's geologic history in Minnesota, Wisconsin, Nebraska, Iowa, Kansas, and Michigan is reflected in its vast dispersion and iron-rich color bands. The Minnesota Legislature chose the Lake Superior agate as the official state gemstone in 1969. The agate from Lake Superior was chosen because it reflects many features of Minnesota. It was produced around a billion years ago during lava eruptions in Minnesota.
