A classic example of the famous Adularia twins from Switzerland. This piece is a large, sharp, thick, well-formed, BEAUTIFULLY twinned crystal that I would classify as being a "near floater" as it's crystallized nearly all the way around, but there is a spot on the base that keeps it from being 100% pristine. This is a Baveno twin and looks fantastic from all angles. There is no "front" side, as each angle makes its case for being the "display" side of the crystal. Whether you like the defined twinning line on one side, or the rigid "teeth" flaring out of the sides seen on another angle, the piece presents something different every 90 degrees in which it's turned. For years, Adularia was defined as a variety of Orthoclase, but now it's defined as a variety of either Orthoclase or Microcline depending upon the habit (monoclinic or triclinic). The rich moss-green color is due to inclusions of "Chlorite", which have created a lovely two-tone crystal. This is a fairly large twinned Adularia from any locality, and the fact that it's Swiss makes it all the more valuable in terms of Alpine material.
