Collectors of fluorescent minerals are familiar with the bright, warm yellow, fluorescent wollastonite from the Franklin/Sterling Hill, New Jersey area. Here is an interesting specimen, rich in wollastonite that fluoresces moderate white under all UV wavelengths. This mixed assemblage rock is from Willsboro, Essex County, New York, and contains large white crystals of wollastonite, small olive green crystals of diopside, and large red/brown grains of colophonite, a coarsely granular variety of andradite garnet. Neither the diopside or colophonite are fluorescent. This specimen measures 65 x 51 x 32 mm, and weighs 159 grams.
