New specimen arrived today!
This specimen arrived today. It is mostly Hardystonite, with some Willemite, and very minor Calcite. The specimen is nearly 4" across. The first picture is natural light, note that most of what appears white in this image is hardystonite, not calcite. Type Locality for hardystonite of Franklin Mine, Sussex Co., N.J. In the second image the hardystonite is violet blue, willemite is green, and minor calcite is red. Note what appears to be a thread running horizontally across the base of the fluorescent specimen is actually a very thin veinlet of calcite. Picture was taken with a 5 watt SW UV 254nm lamp held some 6 inches from the lower portion of the specimen. For some unknown reason the fluorescent specimen is in good focus, for a change! Perhaps my camera auto focus does not like LW UV??
