KT still has several specimens left to photograph from the Kentucky Symposium His Majesty attended, and here are 4 more from that batch! HA HA He hopes that all the pics will load. If not, then a couple may be in the next post, immediately below this one and only feature the pictures.
The first pair of images are from a specimen labeled Zircon, Albite and Siderite from Mont St. Hilaire, but when KT put the LWUV light on it, He saw another mineral grain fluorescing....and decided it must be Strontianite. The pair of pictures was taken at 30X, and the LW lamp was filtered to eliminate blue reflections. So that is pics 1 & 2.
The next pair of photos is of some very nice 30X fluorite crystals from the Thomas Range, Juab Co., Utah. The octahedral fluorites vary from colorless to pale yellow for the slightly larger ones, but in SWUV 254nm they are all a strong uniform, typical of fluorite. Pics 3 & 4.
The third pair of pictures is of a feldspathoid mineral, not commonly seen....Hauyne. KT likes the Hauyne's pale blue natural light color. It lights up a bright orange color in filtered LWUV 365nm. First specimen for The Royal fluorescent collection of this species! 20X. Pics 5 & 6.
And finally the last two pictures are of purple hackmanite from Mont St. Hilaire. The crystalline mass at 20X is a distinctive purple color in natural light. And in filtered LWUV 365nm it lights up with its typical orange response. Pics 7 & 8.
KT had fun taking these pictures! Hope you enjoy them!
