Here we go with 3 more interesting samples!
Here are 3 SW 254nm fluorescent mineral specimens.
First is a dark tan calcite from the Santa Barbara Mine, Mun. de Santa Barbara, Chihuahua State, Mexico. First image is in natural light. The specimen is about 3 in. long in the horizontal direction. The second image shows its nice red fluorescence. IKT used 2 4-watt lanps to get the nice intense color, one from the right and the other from the upper left.
The second specimen is a butt end slab of Eucryptite with minor spots of Scheelite. It is from the Xianghualing Mine, Xianghualing Sn-polymetallic ore field, Linwu County, Chenzhou, Hunan, China. The specimen looks rather like one of KT's friends “gray rocks” in natural light in the first picture, but sure makes a nice showing of red eucryptite and blue-white specks of scheelite in the SW image! Again, 2 4-watt SW 254nm lamps, one on the right and the other on the left of the image.
Finally, here are a couple of t/n sized pieces, both in a 1 in. X 1 in. box. Another non-descript gray rock in natural light, but it lights up like a torch in SW 254nm. This piece was so bright His MajestyI had to back off and use only 1 4-watt light to enable me to get any kind of a photograph of its fluorescence!
Enjoy!
