Many are familiar with the Anza-Borrego Springs calcite mine trail with its wonderous formations and views. Few know of the World War 2 era calcite mine where optical calcite was sought for use in bomb sights. An undertaking by the California Geological Survey in the 1980s led to exploration for more optical clear material. The search was not successful but did lead to a small find of purplish pink discoidal calcite specimens. This is purportedly the finest from the find and it really is special. It has an internal glow and is bright orange under LW (indicator of manganese). The specimen is complete and has very minor chafing at a few edges with one tiny ding. A real prize. This was Kennys favorite specimen.
Locality: Borrego Springs, California
