Mineral Specimen #5065    Fluorite Penetration Twins, Muscovite

Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China

6.1 x 4.7 x 5.1 cm


Two well formed, penetration twinned Fluorite crystals are setting on the edge of the surface of this specimen. The crystals are very transparent with a glassy luster and very smooth surfaces. The color is a very light blue with a purple core. There is another larger, similar Fluorite crystal at the other end of the specimen of the same colors which, unfortunately, is partially broken. The surface of the specimen is covered with bladed Muscovite crystals which are gray to tan in color. There is stalactite growth of these Muscovite crystals connected to the broken Fluorite crystal. The specimen has been hot glued onto an acrylic base which nicely presents the penetration twins.

Condition: Very Good

Flaws: The Fluorite crystal at the end of the specimen at the other end from the pentartion twins is incomplete. There are a few, very small chips on the surface of the penetration twins and some internal cleaves.
