Grape agate, also called grape chalcedony or grape amethyst, is a botryoidal variety of quartz that occurs as clusters of small spheres. Specimen- and gem-quality material is usually purple and sometimes blue-green. Grape agate was discovered in 2014 in West Sulawesi, Indonesia and first entered the global market in 2016. It derives its name from its appearance resembling a bunch of grapes. Despite its common trade name, grape agate is not agate because it lacks banding. Grape agate has been described as a form of chalcedony, but it is actually a form of macrocrystalline quartz (amethyst when purple).
