So members of the Royal Round Table, including KT, are happy!
The specimen is from the Franklin mine, near Ogdensberg, Sussex Co., New Jersey. It is a small hand specimen. It was sold to me as fluorescing orange, though the pictures on eBay are obviously yellow. The first image is in natural light, and the second is in SWUV 254nm. And it looks yellow to me, both in presence and in this image!
Color is of no matter to me, just the fact that it is wollastonite from this location is good enough!
Enjoy the pictures!
