Physical properties
Small, translucent green-yellow fragment; fluorite has Mohs hardness 4, vitreous luster, and cubic crystals with prominent octahedral cleavage. The image is too blurred for reliable identification or property testing.
Formation & geological history
If fluorite, it formed from mineral-rich hydrothermal fluids in veins or cavities, across many geological ages. Its exact origin cannot be determined from the image.
Uses & applications
Fluorite is used as an industrial flux and source of fluorine; attractive pieces are collected or occasionally cut as gemstones.
Geological facts
Fluorite commonly occurs in vivid colors and may fluoresce under ultraviolet light, though fluorescence cannot be inferred here.
Field identification & locations
The color alone is not diagnostic; check for cubic habit, cleavage, and hardness, and compare with other green-yellow minerals. Common deposits include China, Mexico, South Africa, and the United States.
