Of all the amazing minerals I did pick a pretty bland one to be my favorite. Yes, good old calcite. Perhaps because it is so easy to ID and I get a warm fuzzy feeling when people screw it up on lab praticals because they got fooled by the salmon orange or blue variation or more likely its very much engraved in my outdoor recreation. Afterall the awesome cave formations I enjoy when in some silt covered, bat flourishing, dark crevice are all made of this wonderful mineral. Of course as a kid I collected this mineral way to much and thier is still shoeboxes full of calcite vein under my bed (unless my mother found it and turned it into part of the rock garden). Finally who doesn’t enjoy dropping some acid and watching it fizz.
