カラーチェンジフローライト

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.
フローライトはトルマリンのように多色でも有名です。複数の色が層になったレインボーフローライトなども見かけます。
中でも、カラーチェンジフローライトは、希少石で、宝石の通が喜ぶコレクターアイテムでもあるんですよ。
写真のように、太陽光ではサファイアと見違えるようなブルー。ところが、オレンジの朝日や夕陽、ろうそくや焚き火などの炎、白熱電球の光に当たるとパープルに見えるのです。
Florite that changes its expression. Don't you think it leads to the freedom of the mind?
