A sharp, lustrous calcite crystal perched perfectly on limestone. The 3.8 cm crystal is contact twin, with subtle re-entrants around the middle. This crystal is champagne-coloured, with orange hues added by iron oxides. In excellent condition, one nick. One place on the crystal has what seems to be a thin limestone-intergrowth veneer, and inside the crystal there is lively internal play of light. From the John S. White Pennsylvania collection, he acquired it from Skip Colflesh.
