Dear Teresa;
I can say that the clear xls are probably quartz & the pinkish-white ones are probably calcite or a similar carbonate; however, the black blades, bcs there is NO locality, could be ANYTHING. I'm afraid, even taking Jose's advice, that without someone performing some chem tests, those will remain a mystery. I would also want to know what the small white needles, amongst the calcite(?) xls are; they COULD help target a locality, which would key what the black xls are.
Here's another test you might try, if you can obtain a short wave UV; see if the calcites fluoresce, &, what color they do.
Your friend, Steve
