How deep is the hole?

I would do a mm at a time, a mm of dust and couple drops of CA. Let cure then more Dust, more CA. if you have enough dust to fill.
Make sure the stone and dust are dry.

Over fill a bit and re-lap.

I have saved dust and you can easily generate an ounce or two lapping a stone.

As said it does not have to be perfectly flat, just smooth. Flat is nice but don’t waste stone to get it all flat.

Like your Coticule. The flat does not go all the way to the sides, but that’s Ok. You will waste a lot of stone for not much more Real Estate, in my opinion. Just round or bevel the edges lightly.

I agree was pretty happy with where the yellow is. I'll leave that hollow for the toeside and use x strokes.

[Euclid440]

As long as it’s smooth.

I think the better find may be the Yellow/Green Thüringen which I think you may have there.

One of my 2 dollar Swap meet finds is a Y/G Thüringen and one of my best finishers.

I have several Coticules and still not a “big” fan. Not tossing in the trash… but love the Eschers and Thüringen’s.

Are you a patient man?

If so, lap the snot out of the Coti and see what you've got. I think it could eventually be usable and you might have a candidate finisher there.

Alright sorry to keep going with this so long but I completely lapped one side of the maybe thuringian. There black spots with what look like maybe pyrite inclusions? They are only near the end though. Here's a pic

[Euclid440]

Try a razor on it, or do a quick lapping of the other side to see of the spots go through. It is not uncommon for a natural stone to be dramatically different from one side to the other. One inch thickness can represent hundreds of years of sediment, a lot can happen in that time of settling.

It also may not matter, won’t know till you try...

Hone to at least an 8K edge then go to the Thüringen, I often do after a 12K Super Stone.

The Coticule may also be a finisher, but Coticules can be one of the most frustrating stones and can take some time to learn the stone to make it perform. Even when you think you got it down, the stone probably has much more to give.

Some love them, some despise them… perhaps it is why there always seems to be a Coticule for sale in the classifieds.

Yeah you're right I need to stop wondering what it is an find out where the metal meets the stone. I took it for a test tonight, but I will probably need to tweak my routine a bit to see what's up. Thanks again everyone for all the help and opinions; much appreciated!

Alright fellas I keep coming back for more. I'm sorry but y'all are a wealth of information. I lapped the more difficult side of the possible thuringian and found some interesting things;
dry with inclusions
dry close up inclusions/ strata change?
wet inclusions and strata color change
overall wet. That round dot is just light not something on the hone.
Any thoughts guys. Based on the adhesive on the ends, the near perfect match in size and coloring; could this be a barbers delight escher or something similar? Thank you again guys for all your time and opinions!

Looks like too many inclusions to be an escher I would say

[doorsch]

Mhh...i also do not really tend that this is thuringian...not ruling it completely out...

The guess us just a nice fine kind if schist where a mass of these are around in all variations...another pic of one i own which has some pyrite inclusions and a comparable structure to these points you showed...no strata change on this one...i also thought this might be a thuringian but it is not...
