After I got to looking at this specimen, I realized how nice it actually is. The crystals of Dolomite are large and prestine. The largest crystal is 2cm wide. All about matrix matrix are much smaller crystals of either Dolomite and/or Calcite. These are are also perfect rhombs and average 3mm. No damage aside from one little ding, otherwise clean. Nice piece form this famous and classic locality.
