An attractive and elegant fluorite specimen from the famous Yaogangxian Mine, Yizhang County, Hunan Province, China. The specimen features a prominent Twinned cubic fluorite crystal rising distinctly above a pale, finely crystallized matrix. The fluorite displays a beautiful sky-blue to blue-green coloration, with good translucency and subtle internal zoning visible through the crystal. Its sharp cubic form, clean edges and broad reflective faces give the specimen a strong geometric character, Associated with Arsenopyrite and Siderite. The contrast between the isolated blue fluorite cube and the light-colored sparkling matrix creates a very balanced and aesthetic composition.

A classic and highly displayable example from Yaogangxian, one of China’s most celebrated mineral localities, well known for producing high-quality fluorite specimens.
