Picture What's Carnelian Red Color Gemstones? Carnelian is a variety of chalcedony and is a microcrystalline quartz. As a chalcedony, carnelian is formed from the intergrowth of two silica minerals with differing crystal structures: quartz and moganite. Carnelian appears in a vibrant range of fire-orange reds to brown-reds and has a dull, waxy luster (as opposed to the vitreous quality of crystal quartzes such as amethyst). The reddish tints in the translucent stone are due to one of its ingredients: iron oxide. Carnelian can be confused with jasper, which is usually considered a chalcedony. Carnelian is most commonly found in India, Brazil, Siberia and Germany. Most carnelian gemstones are dyed and heat-treated to achieve additional color variations. Carnelian is the birthstone for the zodiac sign of Virgo (August 23 - September 22). For most cultures, from the 15th to the 20th century, carnelian was one of four birthstones for August. In 1912, the United States adopted peridot as the August birthstone, however in 2013, Britain recognized carnelian as a secondary birthstone after ruby. Where to buy Carnelian Red...
