Fluorite Hunan China | Ref.587

This purple fluorite from Hunan, China displays well-developed cubic crystals arranged in overlapping growth. The crystal faces are clearly defined, with sharp edges and a translucency that varies with crystal thickness. Overall, the piece offers a clear view of the crystallization and highlights the natural geometry of the cubic system.

The purple colour of fluorite is generally linked to what are known as colour centres. These are very slight defects in the crystal’s internal structure: at a microscopic scale, a small irregularity changes how light is absorbed, producing the colour. The shade can also be influenced by trace elements and by the crystal’s natural geological environment. The term post-genetic is used when such changes occur after the crystal’s initial formation.

For care, a gentle dusting with a soft brush is sufficient. As with many light-sensitive minerals, it is best to avoid prolonged exposure to direct sunlight to reduce any risk of colour change over time.
