Normal Sudoku rules apply.
KROPKI STONES
- Digits on either side of a white stone (in the same row/column) differ by exactly N, where N is the digit on the stone.
- Digits on either side of a black stone (in the same row/column) have a 1 to N ratio, where N is the digit on the stone.
Solution code: Row 1

Thanks a lot for this amazing puzzle. My head is still spinning from falsifying so many permissible things and proving many contradictions but I got there at the end :)

Thank you very much for creating and sharing another fantastic puzzle. (Only the BLACK stones - pencil marks are invisible for me there.)
