This is a superb, balanced specimen with unusually stunning color to BOTH the species, whereas normally one is good and the other is poor if you are lucky. The crystal is exceptionally fat, gemmy, lustrous, and robust. It is so shiny an dlustrous that it looks polished, but this is natural (the surface actually is slightly curvy, as some of these can be found). Complete all around, this aesthetic specimen stands on its own merits. However, as a bonus, it was featured in the case and the companion issue of Mineralogical Record for the 2008 American Mineral Treasures Exhibition. At that time, it was in the Dave Stoudt collection. Joe Budd Photos.
