This dynamic datolite was dug by hand by Bob Wright from a MN river that runs into Lake Superior- then cabbed by Bob. I places it on a sterling pendant with a texture to mirror the veins of the rocks.



Datolite is a  silicate that occurs in a wide range of colors. Within the region it is unique to the Keweenaw native copper deposits as well as places along the shores of Lake Superior.  Datolite formed when hydrothermal solutions invaded open fractures in the basaltic rocks of more than a billion years ago. It occurs both in veins and has roughly spherical nodules of compact, fine-grained material that takes polish excellently.
