Red Lightning Calcite and Aragonite, Promontory Point, Utah

An interesting little specimen from Promontory Point in Utah. The red fluorescing calcite is like a circular bolt of lightning. The aragonite glows bluish white in shortwave, day old cream in midwave, and off white in long wave. It's also highly phosphorescent (not shown). Neat little piece, shown in SW, MW, LW, and Natural.
