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!
