Fluorite, Calcite, Barite

Update 4/13/18 - Unknown brown inclusions identified as nelenite per this convo https://www.facebook.com/groups/mindat/permalink/10154595717437465/

One of my favorite purchases from Tucson this year was this beautiful fluorite from Inner Mongolia. It is a wonderful fluorescent specimen accented by bladed barites and rhombohedral calcites. What makes this piece unique is the plethora of colors that are included within the fluorite octahedrons themselves. While these colors will appear under the traditional 253.7nm bulbs it can be viewed under 265nm UVC LEDs. I believe this will truly be a specimen for the future as LED technology in that space improves and we get brighter and brighter fluorescent reactions.

Calcite, Fluorite

One of the best pieces of calcite, fluorite I had found during 2017's Tucson show. There's always a lot of calcite and fluorites from the area but this one caught my eye. It was the combination of wonderful octahedral fluorites with colorful calcites under my LW light.
