Description
Celestite is a mineral form of Strontium Sulfate which is a metal. The metal is mixed with Carbon and Sulfur which is used for the red “fire” in fireworks, flares and road signals. Celestite occurs as Crystals and in compact massive and fibrous forms. It is mostly found in sedimentary rocks and is often associated with Gypsum, Anhydrite and Halite. Pale blue Crystal specimens are found in Madagascar.
Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride. It is a widely occurring mineral and is often found with metallic minerals such as Galena and Sphalerite, but also with Barite, Quartz and Calcite. It may fluoresce strongly in ultraviolet light. Although green is the most common color, it can also be red, purple, blue, yellow and white.
