Manganoan calcite

This amazing specimen from the Bor Pit at Dalnegorsk features a calcite crystal that has completely engulfed a smaller one, except for a tiny opening atop where the sharp prismatic termination of the inner crystal shows through. You can actually see the termination of the smaller crystal in a recess in the center of the termination of the larger one, and because the large crystal is so clear, you can see the smaller crystal inside it from every angle.
