Agate Crystal Heart Carving K2 ranging from pale orange toAgate is a rock consisting primarily of cryptocrystalline silica, chiefly chalcedony, alternating with microgranular quartz. Agate is a translucent variety of microcrystalline quartz. It is used as a semiprecious stone when it is of desirable quality and color. Agate generally forms by the deposition of silica from groundwater in the cavities of igneous rocks. These structures produce the banded patterns that are characteristic of many agates. Agate
