Grape Agate Sphere

A natural, polished grape agate sphere. Grape Agate is a market name for purple aggregates of tiny quartz crystals with a botryoidal (spherical) habit. It is not technically an agate but rather botryoidal purple chalcedony. This mineral is characterized by its purple color and spherical crystal formations that resemble bunches of grapes. Grape Agate is relatively new to the market, having been discovered in Indonesia, and is considered a rare and valuable stone. It has a Mohs hardness of 7.
