Creedite Crystal Mineral
HISTORY, NAME, LOCALITIES: Creedite was first discovered near Creede, Colorado, in 1915 and recognized as a new mineral species the following year. It is named in honor of Creede. Creedite is an uncommon mineral and few localities yield collectible specimens. Notable localities are found in Mexico, Bolivia, Greece, South Africa, France, and the United States (Colorado, California, Nevada).
MINERALOGY, PROPERTIES, OCCURRENCE: Creedite [basic hydrous calcium aluminum fluorosulfate, Ca3Al2(SO4)(OH)2F8·2H2O], pronounced CREED-ite, crystallizes in the monoclinic system as prisms with diamond-shaped cross sections and sharp, asymmetrically slanted terminations. Crystals often form characteristic radiating, spherical groups. This uncommon mineral has a Mohs hardness of 4.0, perfect cleavage in one direction, vitreous-to-greasy luster, and a specific gravity of 2.7. Crystals are translucent to transparent; traces of iron often impart a reddish-orange or brownish-red coloration with prominent color zoning. Creedite forms as a secondary mineral in the oxidized upper zones of sulfur- and fluorine-rich mineralization, most often of barite or fluorite deposits.
METAPHYSICAL PROPERTIES, LORE, USES: According to metaphysical beliefs, creedite aids in the understanding of others, helps heal emotional trauma, and promotes clarity of expression. Creedite has no technological uses.
COLLECTORS’ INFORMATION: Mineral collectors value creedite for its rarity, unusual reddish-orange color, complex chemistry, and distinctive crystal forms, notably its characteristic radiating, spherical crystal groups that make interesting display specimens.
