A large, single, twinned crystal of Calcite. This particular habit is known as a "Poker Chip" because of its disc shape. This is a very large example of this habit, usually the crystals are also the general size of a poker chip. This is classic Mexican material unique to this location. It does fluoresce under UV, a pink/orange under SW and a bit more orange under LW, but a bit pale. There are a layers colored white, with a slight pink cast, light gray and clear with the clear in the middle. The specimen is in good condition with no appreciable brusising. There are cleavage cracks readily visible in the photos.
