Fluorescent Minerals
Two sides of the same rock under SWUV - orange caliche and red calcite, along with green and two unidentified shades of blue. The green is likely opal.
Second view again under white light. 5"x3"x1.5" (Pima County)
A red and blue piece - the red is calcite, and the crystalline blue may be calcite as well. Or hydrozincite. Or fluorite. Color is not always a reliable diagnostic indicator in the fluorescent world. 3"x3"x2" (Pima County)
Two-toned piece with one face of orange caliche and another of red calcite with substantial crystalline blue, as well as a few pink streaks. 6"x7"x3" (Pima County)
