Unused item, purchased at the Tokyo Mineral Show and stored at home. #kaorin_natural_stone Although unused, it has been stored for a while since its purchase (around 2011). There are some minor scratches (see photo 4), but I believe it should not affect usage. Size: Length: 9.5 cm (longest part) Width: 4.5 cm (approximately the middle of the long side) Thickness: 5 mm Please allow for some margin of error. Please consider purchasing only if you understand that this is a self-inspected, long-term home-stored item. I kindly request that those who are concerned about minor details refrain from purchasing. #aventurine #powerstone
