Fluorine or Fluorite belongs to the group of halides. It contains calcium and fluorine. Its chemical formula is CaF2.

FLUORINE crystals are often cubic but also octahedral and offer magnificent translucent specimens generally purple, green, yellow, blue and more rarely pink.

Its massive form is also transparent or translucent. The hardness of Fluorite is equal to 4/10 on the Mohs scale (10 for diamond) and its density varies between 3 and 3.3 (1 for water). The line on porcelain is white.

The name Fluorite comes from the Latin word fluere which means to flow, in the sense that Fluorite flows when it melts.

CREEDITE belongs to the halides group. It contains calcium, sulfur, aluminum, fluorine, and water.

Its chemical formula is Ca3Al2(SO4)(F,OH)10.2H2O.

It usually appears as acicular crystals in lamellae or aggregates. Its color is most often yellow-orange but it is also found in colorless or violet. The hardness of Creedite is equal to 3.5/10 and its density is greater than 2.7 (1 for water). The line on the porcelain is white.

CREEDITE is a fairly rare mineral that owes its name to the town of Creede in Colorado (USA) where it was discovered in 1916.
