Description
Wollastonite on calcite from Nobel Pit, Sterling Hill Mine, Ogdensburg, Sussex County, New Jersey.
FOR BEST FLUORESCENCE YOU WILL NEED A QUALITY, FILTERED 254nm SHORT WAVE ULTRAVIOLET LAMP.
You will get some fluorescence with a 365nm long wave ultraviolet light, but this one reacts much better to short wave UV.
The wollastonite fluoresces a golden yellow, and the calcite fluoresces a magenta color under 254nm short wave UV. With 365nm long wave UV, you will see the wollastonite but not much of the calcite fluoresces.
Size: 75 x 35 x 20 mm. 80 grams.
