Mineralpedia Details for Zircon
Named for the Arabic word zarqun, which is "thought to be derived from the Persian zar, for 'gold,' and gun, for 'color.'” Extremely common and widespread, Zircon is found as an igneous and metamorphic accessory mineral, large crystals in pegmatites and carbonatites, and in sedimentary rocks and sands. Despite its frequency, fine, gemstone-quality crystals are rare. Nearly all zircon fluoresces under UV light. Can be radioactive.
