Every Japanese natural stone I have sold since 2008, with the photos and the notes I wrote at the time — the mine, the hardness level, the size and the stone code.
Nothing here is for sale. Mines close and stones run out, so most of these will not come back. But the notes are useful if you are trying to place a stone you own, or one you saw somewhere and want to understand.
For the stones I have now: Japanese Natural Stones
