Fluorite has only been shown in their first form when Gems are born before being shaped by Kongo-sensei. They are shown to have a crystalline body and long hair.
Fluorite has not been shown talking or interacting in any way other than during the moment of their discovery. At that time, they were found twitching on the ground next to Red Diamond and Kongo-sensei.
Fluorite is the second Gem to be born. They were found by Kongo-sensei and Red Diamond on the Beach where all Gems are born. Due to their fragility, Kongo-sensei and Red Diamond carved a shelter out of a large piece of quartz, which currently stands as The School. Not much else is known about them.
- Mineral: Halide
- Chemistry: CaF2
- Color: a wide range of colors.
Fluorite (also called fluorspar) is the mineral form of calcium fluoride. It belongs to the halide minerals.
Fluorite is a colorful mineral in both visible and ultraviolet light, and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals.
Fluorite is allochromatic, meaning that it can be tinted with elemental impurities. Fluorite comes in a wide range of colors and has consequently been dubbed "the most colorful mineral in the world". Every color of the rainbow in various shades is represented by fluorite samples, along with white, black, and clear crystals. The most common colors are purple, blue, green, yellow, or colorless. Less common are pink, red, white, brown, and black. Color zoning or banding is commonly present. The color of the fluorite is determined by factors including impurities, exposure to radiation, and the absence or voids of the color centers.
The word fluorite is derived from the Latin verb fluere, meaning to flow.
- They might be the "Pink-Fluorite" used by the Lunarians as a weapon against the Gems during Chapter 18.
