color change florite

Florite is called fluorite in Japanese. Its main component is calcium fluoride.
The stone may be more famous in the power stone industry and the camera industry than in the gemstone industry.
Florite is named after the Latin word "fluere" (flowing).
Among power gemstones, it is said to channel stagnant chi and balance both mind and body with its high vibrations.
And with its wonderful properties for all types of light, from ultraviolet to visible to infrared, flow light has become a coveted lens in the camera industry as an ultra-premium lens. So it is truly completely transparent and allows all light to flow through. Even today, lenses made with fluorite are very expensive, even though they are man-made, but the best photographers are acquiring them.
