Franklin & Sterling Hill


Important:  Fluorescent minerals require a special ultraviolet lamp to view them (normally, a short-wave UV lamp).  It's worth it to get a good lamp.

The color response of your computer's monitor may not be the best representation of the photographs. The colors shown in the photos, at least as they appear on our office monitor, are the most accurate representations we were able to capture with the limitations of the camera.
