Fluorite is a colorful mineral composed of calcium fluoride (CaF₂), known for its wide range of colors and perfect octahedral cleavage. This carved point showcases fluorite’s internal zoning and transparency, often displaying bands of purple, green, blue, or clear layers depending on trace elements present during formation.
Features:
-
Composition: Fluorite consists of calcium and fluorine and crystallizes in the isometric (cubic) system, often forming cubes or octahedrons in nature.
-
Optical Properties: Exhibits strong fluorescence under ultraviolet light and sometimes thermoluminescence. Its color variability is caused by trace impurities or radiation exposure during formation.
-
Formation: Fluorite commonly forms in hydrothermal veins, especially in association with lead, silver, or zinc ores. It can also occur in sedimentary and igneous environments.
-
Carved Point: While naturally occurring in cubic or octahedral forms, this fluorite has been shaped into a polished point to highlight internal banding and color zoning.
-
Educational Value: Useful for studying mineral properties like cleavage, fluorescence, and crystal systems, as well as mineral coloration due to trace elements.
This specimen is ideal for classroom use, mineral collections, or display as an example of both natural beauty and crystal structure.
