   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.).
