Two, large, tabular, glassy and gemmy, colorless crystals of celestine, to 7.8 cm across, are separated by a sliver of matrix. The large crystal is doubly terminated and pristine while the other large crystal is just slightly contacted on the back side. Celestite is very RARE at this locality and this piece is one of the best I know of from the mines here. It is dramatic, and 3-dimensional, and holds its own with other locales. For Naica, though, it is nearly off the charts.
