Amethyst, Mamuju Area, Sulawesi Barat Prov, Sulawesi island, Indonesia
Size- 16.5cm x 11.0cm x 16.0cm
A unusually large specimen of sparkling purple balls of the so called grape agate from Indonesia. Recent study on these have shown them to be amethyst crystals. My only specimen this size left. Most specimans this size are extensively damaged. Specimans are getting harder to get and expensive as the mines are near depleted.
