Lake Superior Agate
Lake Superior Agate is widely known as a tumbling rough. It is so popular in the Great Lakes area that the Minnesota legislature designated it as the official "state gemstone".
Lake Superior Agate is typically a banded material - often concentric - but sometimes has eyes and mossy patterns. The red, yellow, orange and brown colors are a result of iron staining of agate material.
Our Lake Superior Agate mix consists of small nodules and nodule fragments found in the Great Lakes area. It is a tough, dense material in pieces that range from 1/4" to a little over 1" in size. It takes a great polish. Photographed wet to show full color.
