Chalcedony is a type of quartz that is made up of tiny intergrowths of quartz and moganite, two silica minerals. It has a compact, fibrous structure, a waxy luster, and a splintery fracture. Chalcedony can be found in a variety of colors, including bluish-white, gray, yellow, and brown. Chalcedony forms in sedimentary and volcanic rocks when a silica-rich solution fills a cavity in the rock and deposits crystals along the walls. Chalcedony varieties include agate, onyx, carnelian, and sard. Agate is chalcedony with color bands, and onyx is agate with alternating bands of white and black or dark brown. Carnelian is translucent red chalcedony, and sard is translucent brown chalcedony.
