Rare - Grape Agate "Batu Manakarra" Bothroidal Chalcedony - Height: 240 mm - Width: 175 mm- 2661 g

Particular example of Grape Agate, a mineral made up of purple botroid chalcedony, i. e. small spheres that formed naturally together.
Chalcedony forms in different environments, often inside geodes where it covers the cavities with mamellar shapes.
Its discovery is relatively recent and comes from Indonesia: perfect for expanding your collection with a truly unique specimen!
This sample is particularly large and of excellent quality. It has been mounted on a black wooden base with a particular steel grip system, very beautiful and elegant, a natural history object with great aesthetic charm.
