RARE | Batu Manakarra Grape Agate Botryoidal Amethyst Rough Crystal Specimen #GP000TIR02

Grape agate is a unique and visually stunning gemstone that's highly sought after by collectors and enthusiasts. It's formed from chalcedony, a type of microcrystalline quartz, and is found in the volcanic rocks of Mamuju area in West Sulawesi, Indonesia. What makes grape agate so special is its distinctive resemblance to a cluster of grapes, with small, round balls of deep purple crystals that grow together in a compact formation. The crystals themselves are believed to have formed from hydrothermal fluids that percolated through the volcanic rocks during the late Miocene epoch, which occurred approximately 5 to 23 million years ago. Each grape agate is completely unique, with its own distinct pattern of crystals that can vary in size and shape. They're typically found in small pockets within the volcanic rocks and can be difficult to extract without causing damage. This rarity, combined with their striking appearance, makes grape agates highly prized by gemstone collectors and enthusiasts alike. In summary, grape agates are a fascinating and visually stunning gemstone that offer a glimpse into the geological history of Indonesia's volcanic rocks. Their unique formation process, age, and location make them a truly one-of-a-kind addition to any gemstone collection. Berat: 221 gram
