Mamuju Area, Sulawesi Barat Province, Sulawesi Island, Indonesia
This is a great rarity from this location: bi-colored translucent amethyst spheres with good color grown on yellow, green and white chalcedony matrix (also well known as chalcedony or grape agate). The amethyst spheres show a darker zoning in the centers. Well crystalized on three sides – the bottom was extracted from the rock (first photo). An extraordinary piece with rare colors and construction!
