Thread: Mint green hone with orange dots

I recently purchased this hone on the bay from a GB vendor. It came in a typical wood storage, but hasn’t been used with oil in the past.
It’s a hard hone, maybe novaculite, so it could be a CF or LI. But I have not seen a hone in this mint color stained with lighter colored patches and with orange and dark/black dots.







Any idea what it is?
