Fluorite with Barite
Komshejeh Mine, Komshejeh, Ardestan County
Esfahan (Ishfahan) Province,
6.7 x 6.2 x 3.4 CM (cabinet)
Zoned cubes of Fluorite with complex stepped etching on most faces in an attractive cluster from Iran. The associated bright white Barite blades adds a nice contrast. The Fluorite is mostly a blue color with a violet to pink core best seen in the largest crystal. Some color change is noted under different light sources. In very good condition as seen. Not much Fluorite from Iran makes it to the western mineral markets, this specimen is especially attractive and reminds us of the structure of some Spanish Fluorite but is clearly different on close exam.
We see very few Bournonites from Trepka and almost never of good esthetics. This is a very pretty specimen with the best quality we have ever seen. The most prominent Bournonite crystal is perfect, undamaged 1.4 CM in diameter and has bright metallic luster. It is a textbook quality twin with cogswheel form on the edges. The whole piece has choice contrast with brilliant Pyrite forming most of the matrix. Trepka has been known as an excellent source of other Sulphides. This new find was small but had impressive Bournonites which is certainly newsworthy and exciting.
