What Is Moss Agate Made Of? Moss Agate is a form of Agate, a member of the Chalcedony group of stones, which in turn is a member of the large Quartz family. All types of Quartz are composed from silica (otherwise known as silicon dioxide), but differ due to their crystal structures. Chalcedony gems are microcrystalline in structure, which means you can't see the crystals inside the stone. Other types of Chalcedony gemstones include Jasper, Carnelian, and Chrysoprase.
