Can you please help me identify this crystal?

0 votes

It has a subtle color, very shiny, small black specks, and very small in size, it was photographed with macro. Thank you very much!

Black specks are inclusions, small impurities,  in the crystalline structure. I think calcite but that is in no way absolutely correct. It is a guess.

I guess this is calcite, but could be wrong

Well, the easiest way to tell if its calcite is to do an acid test. See if you can put a drop of acid, even vinegar, on a crystal face with a dropper, and then see if it fizzles with little bubbles. If it does, it is a carbonate and most likely calcite.
