Purchased over 10 years ago from a friend who loves stones. Never used with water. It has only been displayed. An unknown stone. I recommend placing it in a bright room. It's a bit heavy, so please handle it with care. I don't know much about stones, so I don't know the details of the type, etc. If you know about stones, please consider it. It's small, but it weighs 2.4kg. The width is about 13-15 cm. Please refer to the photos. Color: Green Type: Raw Stone
