Vigezzite on Ferrocolumbite, Beryl Pit, Quadeville, Ontario

EDS by Nikscher suggests these are likely vigezzite, but I'd certainly like to get more work done on them. The right hand photo is the normal color, I presume the left is stained by hematite. Surprisingly common in the vuggy white albite, sometimes completely carpeting tabular ferrocolumbite xls to a few mm in size. Can be very beautiful, but very tiny, well under 1mm. Both photos associated with colorless albite blades, with opaque creamy caps of, presumably, another feldspar.
