The Lake Superior agate is a type of agate stained by iron and found on the shores of Lake Superior. Its wide distribution and iron-rich bands of color reflect the gemstone's geologic history in Minnesota, Wisconsin, Nebraska, Iowa, Kansas, and Michigan. In 1969 the Lake Superior agate was designated by the Minnesota Legislature as the official state gemstone. The Lake Superior agate was selected because the agate reflects many aspects of Minnesota. It was formed during lava eruptions that occur
