Fluorite crystal carries in its wonderfully intricate designs the spiritual qualities of symmetry, beauty, lucid dreams, and even genius. Its name comes from the Latin word fluor, meaning "flow," but today, it is used to describe the crystal's fluorescence – its ability to glow under ultraviolet light.. Throughout history, Fluorite has been one of the most prized …
Fluorite or fluorspar is the mineral form of calcium fluoride (CaF 2).The mineral may occur as massive (Fig. 1.15) or vein-type deposit, in association with metallic minerals forming a part of mineralization.The associated minerals include barite, calcite, quartz, galena, sphalerite, and pyrite (Fig. 1.16).The vein-type mineralization is of hydrothermal origin.
