3.7" Purple Botryoidal Grape Agate - Indonesia
This is a purple grape agate specimen from Sulawesi, Indonesia. It shows purple chalcedony formations and a botryoidal structure from which it earned its name.
Grape agate is the name given to a purple, botryoidal form of Chalcedony found in the Batu Manakarra mining district on the Sulawesi Island of Indonesia. It forms in clusters that often resemble bunches of small grapes, and colors can range from pale to deep purple to green. Some specimens can be quite sparkly due to minute quartz crystal growing on the spheres. Grape Agate is a relatively new material on the market, first being exported from Indonesia around 2015.
