Description

Creedite is a rare hydroxylhalide mineral that formed from the oxidation of fluorite ore deposits.  It ranges in color from colorless, white, violet to orange.  Creedite gets its name from Creede Quadrangle Colorado where it was first found 1916.  It was later also found in Nevada, California and Chihuahua, Mexico.  Other world locations are in Eastern Europe in Tajikistan and Kazakhstan.

Fluorite, also referred to as fluor-spar, is a mineral composed of Calcium Fluoride.  It is a widely occurring mineral found worldwide and is often found with metallic minerals such as Galena, Sphalerite, Barite, Quartz and Calcite.  Fluorite may fluoresce strongly in ultraviolet light which may be due to the presence of some impurities such as Yttrium.  Blue is the most common color but red, purple, green, yellow and white are also frequent.  It can be used in high performance telescopes, camera lens, enamels and in the making of opalescent glass.
