Botryoidal Chalcedony (Grape Agate) from Mamuju, Indonesia

Dimension: 9.3cm x 7cm x 4.2cm
Weight: 223g
Locality: Mamuju area, Sulawesi Barat Province, Sulawesi, Indonesia
 
A stunning display Chalcedony specimen of the so-called "Grape Agate".  A combination of fine brilliant purple radial aggregates "balls" that resemble a bunch of grapes with wonderful three-dimensional cavernous form and notably velvety luster.  Both sides are very well crystallized with beautiful colors, this one really stands out as a real treasure in my mind.
 
The color of Chalcedony from this locality can range from deep purple to very pale amethystine or whitish shades.  Poorly colored ones sometimes get dyed to reveal a more violet colour.  There are also less commonly green ones (colored by inclusions of some clay mineral), and even specimens with purple and green spherules together.
