Physical properties
Hardness: 4 on Mohs scale. Color: Pale translucent green with slight banding. Luster: Vitreous (glassy). Crystal structure: Isometric (cubic). Cleavage: Perfect octahedral. Specific gravity: 3.175–3.184.
Formation & geological history
Formed through hydrothermal activity, typically in veins where mineral-rich hot water passes through cooling igneous or sedimentary rocks. Can be found in deposits ranging from Paleozoic to more recent geological eras.
Uses & applications
Primary use is industrial as a flux in steel making and aluminum production. High-grade specimens are used in optics for lenses. In this form, it is used for jewelry, lapidary arts, and decorative beads.
Geological facts
Fluorite follows the property of fluorescence; many specimens glow blue or purple under UV light. It is often called 'the most colorful mineral in the world' due to the huge variety of colors it can display.
Field identification & locations
Identify in the field by its distinct 4-directional cleavage and relative softness (it can be scratched by a steel knife but not a copper penny). This specific specimen is found in abundance in China, Mexico, and South Africa. Collectors should look for its characteristic translucency and internal geometric fractures.
