Chalcedony, a microcrystalline form of quartz, can form in a variety of shapes and colors, with the red hue typically resulting from the presence of iron oxide impurities. They can be found in various formations, including stalactites, nodules, geodes, and botryoidal clusters.
Moroccan red chalcedony is primarily found in Morocco, a country renowned for its diverse and high-quality mineral specimens. It forms in volcanic and hydrothermal environments where silica-rich solutions precipitate chalcedony over time.
Chalcedony has a Trigonal crystal system with a hardness of 6.5-7 on the Mohs scale. It possess a waxy to vitreous luster and it translucent to opaque.
