This large and striking calcite crystal, with its beautifully striated faces, formed atop a small knob of matrix, which you can see a little bit of on the bottom of the specimen - so that it was able to form completely almost as a floater, with faces even on the underside. What is really weird about it is that there is a thin ridge of massive calcite that the crystal appears to have formed around, which you can see running right through the middle of the crystal and partially exposed on the underside. That is where the slight bit of color is coming from (it has some iron oxide in it). A very Russian-looking crystal, but from Charcas!
