Datolite almost always come in the form of crystals, and there is only
one place in the world where the datolites come in form of porcelianlike
solid nodules; the copper ore regions of the Upper Peninsula of Michigan.
Such datolite nodules are commonly white, but some of them come in a variety
of colors that make them even rarer and more desirable. They almost always
come in small sizes, from marbles to baseballs and I have seen few specimens
as big as basketballs at Seaman Mineralogical Museum at Mich. Tech. University
in Houghton, Michigan. Their uniqueness, colors, beauty, nearby locations,
and rarity are the reasons why they're my favorite mineral, and the best
thing is that since I live in Michigan, I get to try my chance finding
them each summer! I also would greatly appreciate any information on where
to find datolites (like where is the mines of Superior, Nassau, Star, Bumblebee,
datolite fissures, etc.).
