Obsidian raw stones from Shirataki, Engaru, Hokkaido. Mining is now prohibited, making these very valuable. I washed them with water, but as they are raw stones, there may be dirt, chips, scratches, and some remaining stains. Please purchase if you understand natural stones. This is the second example following the clay figures from Hakodate City in Hokkaido, and it is the oldest national treasure in Japan. Shirataki obsidian is a rare and valuable stone that is difficult to obtain because mining is now prohibited. This is a set of 3 obsidian stones. They come in various shapes. My father collected these as part of his collection and kept them carefully at home. I feel they are stones with a lot of power. When I send them, I will purify them with a cleansing solution. I would like to sell them to someone who will cherish them and who loves obsidian.
