Weight: 536g

Locality: Mamuju area, Sulawesi Barat Province, Sulawesi, Indonesia

 

A stunning large cabinet specimen of Chalcedony (also called "Grape Agate") from Mamuju, Sulawesi, Indonesia. 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. The spheres are singularly larger than most from the find and the color trends to more of a lighter lavender and silvery-purple hue in areas, but for the most part, it has some of the best color with the finest luster you will see in this material. Both sides are well-crystallized with a 3-dimentional structure, outstanding!

 

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 like this example.  Comes with a high quality copper wired display stand as pictured.
