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 very few 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.).
