Notes specific to this specimen: These stromatolites from the Gunflint Iron are so incredibly unusual. Every one is so unique! I’ve never seen such a variety of pattern and color as we do in these. This one has purple, red, white, yellow, brown, grey, black and more! This piece is wedge-shaped, so we polished two perpendicular sides to show the longitudinal and cross cut of the colonies. Beautiful piece!
