This is the Fluorite and Quartz combo specimen, wide around 8cm, from Inner Mongolia, China. Fluorite crystals are transparent, have obvious geometric shapes, and bright luster, looks so shiny as gemstones. One smaller Fluorite crystal, outstanding on top of the Quartz, which makes the shape of the whole specimen more interesting! Very rare shape! 

(Note: Longest quartz has one restore place, due to quartz broken while mining it.)
