A spectacular leucophanite specimen with yellow fluorescing zircon throughout and red fluorescent calcite
Leucophanite is only found in a handful of places around the world. To the best of our knowledge only Norway produces massive habit leucophanite with large display specimens. They are bright and beautiful, best under midwave but great shortwave UV. We rarely see pieces of any size.
"Leucophanite is an inosilicate mineral with the chemical formula (Na,Ca)2BeSi2(O.OH.F)7. It may contain cerium substituting in the calcium position.
It occurs in pegmatites and alkali igneous complexes as yellow, greenish or white triclinic crystals and has been found in Norway, Quebec and Russia.
It was first described from the Langesundfiord district of southern Norway in 1840. The name is from the Greek leucos for "white" and phanein for "to appear" in allusion to the common white color. "(Wikipedia)
A major component of rock collecting (for us) is simply getting out in nature. A buddy dragged us out to a very remote area here in middle Tennessee to hunt for fluorescent green agate. Since we consider ourselves pure "Glow Hounds" we weren't anticipating any glow rocks, just the beauty of the area, but we brought our UV lights anyway.
