Another specimen out of the Seaman Museum - a gorgeously crystallized copper, enclosing matrix so that the matrix forms a contrasting backdrop for the crystallized branches. These is not the more common chunky crystal type from Michigan, but the much more uncommon dendritic form, with spinel twins ranged along spines. Displayable from either side - the copper wraps 360 degrees around the matrix!
