Fluorite has been used for centuries as a flux to melt metals from ore more easily and to allow slag to flow away better. For this reason, fluorite is also called fluorspar. Fluorite can have all kinds of colours: white, yellow, orange, pink, brown, green, blue, purple and transparent. The crystal shape is clearly visible: usually a regular octahedron. These facts make the mineral attractive to collectors. The phenomenon of fluorescence is named after this gemstone. When working metal, it was discovered that fluorite glows in the dark if it has previously been in daylight. The element fluorine, discovered in 1886, also derives its name from fluorite. Fluorite is a real study and thinking stone. It helps to see the big picture in the study material and to make connections with existing knowledge. This makes it easier to organise the information and to absorb the material better. This mineral brings you to your core in a gentle yet fast way. It brings out the best in you, both physically and mentally. Because fluorite comes in so many colors, it was and is often used to imitate other gemstones.
