Raw obsidian stone from Shirataki, Engaru, Hokkaido. It is now prohibited to mine, so it is very valuable. It is a stone with red and brown colors among the obsidian. Shirataki, Engaru, Hokkaido is the world's first-class obsidian producing area. The obsidian from Shirataki, Engaru, was designated as the second national treasure in Hokkaido. The obsidian from Shirataki, Engaru, is now prohibited from mining, so it is a rare stone that is difficult to obtain. My father collected it as a collection. I have kept it carefully at home. I washed it with water, but as it is a raw stone, there may be dirt, chips, scratches, and dirt that cannot be removed, but please purchase it if you understand natural stones. When we send it, we will purify it with a purification liquid. I would like to give it to someone who will cherish it and to those who love obsidian.
