Wabigoon Lake Rocks are the concretions formed over time by the cementing together of layers of clay and silt. These concretions are most likely deposited some
10000 years ago when glaciers left the area. The holes have been formed by gas bubbles or a soluble mineral in the concretion that has since dissolved. Every piece is different and unique. No two are
the same. We can not guarantee colours or bead styles.
