Nat Fluorite from India 3.51
Fluorite (often referred to as “fluorspar”) is a highly colorful, naturally occurring mineral composed of calcium and fluorine (CaF₂). Renowned for its vibrant banded colors, cubic or octahedral crystal shapes, and ability to glow under UV light (a phenomenon named "fluorescence" after the stone), it is a favorite among mineral collectors.
Key Characteristics
- Chemical Formula: CaF₂
- Hardness: 4 on the Mohs scale (too soft for everyday jewelry)
- Crystal System: Isometric (often forms perfect cubes and octahedrons)
- Colors: Ranges from colorless to yellow, green, blue, purple, pink, and even brown/black due to trace impurities and radiation.
Why It’s Unique
- The Origin of Fluorescence: Fluorite is highly reactive to ultraviolet light. The scientific term "fluorescence" was coined specifically because it was first widely observed in this mineral.
- Industrial Importance: It is the primary natural source of the element fluorine, which is used in everything from hydrofluoric acid to toothpaste and semiconductors.
- Mineral Collecting: Because it easily forms stunning, glassy, and vividly zoned geometric clusters, it is a staple for both museum displays and private collectors.
