Fluorite on quartz – Yaogangxian Mine, Chenzhou, Hunan, China

 Extremely interesting fluorite from the famous Yaogangxian mine in China.

 Within the lilac to light blue, stepped fluorite crystal is another crystal, clearly visible due to the fluorite's transparency. On the reverse side are some quartz and muscovite; the inclusion, judging by its crystal form, is likely feldspar.
