Wollastonite and Calcite, Sterling Mine, Sterling Hill, New Jersey


This is a light-colored, granite-like rock that predominantly contains wollastonite crystals in a calcite groundmass, with other unidentified mineral components.  It was collected from the Sterling Mine, Sterling Hill, Ogdensburg, New Jersey.  Under short wave UV the wollastonite fluoresces a bright warm yellow color, and the calcite responds with dim red/orange glow.  This specimen is not significantly fluorescent under long wave UV.  The size of this piece is 53 x 28 x 16 mm.

 Short Wave UV (254nm)
