Intergrown, slender, tabular, translucent, snow-white calcite crystals to 6 cm across are dramatic enough, for most people. Here we have those flat, sharp discs perched on sparkling orange spheres of stilbite, to 7 mm across that form a matrix under the calcites. The calcite fluoresces a light pinkish orange color... Very pretty! I have seen only a very few stilbites from this locality, said to be quite old. This one turned up in an old collection in California in 2003, and I then sold it into the Stoudt collection of Mexican minerals. Although not in the Heck collection of Mexican minerals as are most others in this update, this piece is from the Stoudt collection which I also recently acquired, and so fit well with the larger update
