Blue Purple Fluorite Specimen

Blue Purple Fluorite Facts

Blue-purple cubic Fluorite from Xinjiang, China is especially interesting because Xinjiang is not as commonly seen in the crystal trade as some other Chinese fluorite localities, such as Fujian, Hunan, or Inner Mongolia.

The blue and purple colours in Fluorite are usually caused by a combination of trace impurities, natural irradiation, and colour centres within the crystal structure. Pure Fluorite is colourless, but tiny structural changes and trace elements can affect how light is absorbed, producing blue, purple, green, yellow, or other colours
