Thread: I think it's a combination coticule

This old coticule , looks realy nice . Put sone cyanolide glue in the crack to prevent spliting , any further .

It does look like a crack, but it is actually a vein or an inclusion of some other mineral.

Just a wild speculated guess, does the rubbing stone have an in-between layer that looks more orange like? My guess if it does it looks a lot like a La Grise I have

It’s hard to tell since the transition from coticule to BBW isn’t as clear in the rubbing stone as it is in the big stone. This photo is a pretty accurate version of what I see when I look at the slurry stone.
