You may not initially suspect Datolite when looking at this stone, this unusual massive form of this mineral is not common and is quite unknown outside of a few dedicated collectors. Typically Datolite is a completely transparent and colorless (even occasionally light green!) facetable gem. On the shores of Michigan's Lake Superior are found nodules of Datolite that are remarkably unremarkable on the surface - when sliced and polished however these can come alive with superb color - oranges, reds, yellows, a nearly full spectrum is known. These are found in association with Copper deposits in Michigan's upper peninsula so there is actually quite a bit of metallic, native Copper throughout the cab - dynamic and attractive look. This one has a fair amount of matrix material that is grassy green, adding even more contrast than is usual with these.
