Thread: I think it's a combination coticule

Hello all.

I've been lurking on SRP for many years and finally signed up - once I discovered the new location.

I have what I think is a combination coticule and a rubbing stone that I know is a combo, but from a different vein.

I know it's hard to tell from photos, but can anyone on the forum help me identify these stones?

By the way - notice the pencil-marked price? Indicates how long ago this stone was sold.

Nice stones, both are natural combination coticules. To tell which vein is nearly impossible for these vintage stones. The wavy line between Coticule and BBW is somewhat typicall for stones from the Old Rock mine. But the stone itself does not look like a La Veinette, so the stone might have been mined in the Old Rock mine but not from the Old rock (=La Veinette) layer. But honestly this is only guessing. Nobody but the old miners could really tell. Nice find anyhow. If it works fine for you everything is perfect!

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.

Very nice. Just got one in the mail today. Wish the price had been that low.

Either way, some very nice stones, Coticules have given me headaches but also much joy; they're a very interesting stone to figure out and learn about

No kidding ; {

Still trying to figure this one out. It’s the only coticule I have and seems pretty hard. I have tried to use it to set a bevel with mixed results and then tried to use it as a finisher after Norton 4000/8000 0 again mixed results.

I think there was an old curse, “may you live in interesting times”. Seems to apply to this stone for me.
