This one was hard to photo and do justice. They were from a find in 2004. Calcite with unusual complex twinning, with excellent color, luster, and transparency. Stacked crystals seen on the upright photo. Take a look at the photos on mindat.org. to get a better idea. I did not know about these until one showed up in the collection. ex Glenn Davidson collection. ex Weinrich Minerals specimen |
