Wonderful Grape Agate Cluster with a custom stand. Grape agate refers to a type of chalcedony that is known for its distinctive appearance, resembling a cluster of small, grape-like spheres. The proper mineralogical term for grape agate is "botryoidal chalcedony." Botryoidal refers to a rounded, globular, or grape-like formation. It forms through the concentric growth of chalcedony around a central nucleus. This process results in the characteristic grape-like clusters of small, rounded structures. Chalcedony is a type of microcrystalline quartz. It often occurs in massive form and is composed of tiny quartz crystals. When chalcedony forms in botryoidal shapes, as seen in grape agate, it creates a unique and visually appealing texture.
