Margarosanite - Franklin, NJ

Margarosanite from Franklin, NJ. The first pic shows a beautiful face under shortwave UV. The 2nd pic was taken using the Convoy 365nm LW flashlight. This light has the ability to light up rocks not normally thought to be LW fluorescent. Although not great color, it can be a valuable tool in the field when examining unknown rocks. Any hint of fluorescence means the specimen should be examined more closely under SW UV.

I'm not sure what the reddish fluorescing areas are - perhaps a Franklin specialist can help?
