Ammonite and Nautilus

Recieved these in the mail today.  I have several ammonites, no nautilus, and no polished ammonites.

 

These arrived today and are absolutely gorgeous.  I like the ammonite, but to be honest I fond the Nautilus absolutely stunning. 

 

Not certain if that is opal on the shell or not but it is gorgeous.

 

Just thought I would share.

Very nice indeed.:)

The siphuncle on the nautilus is very clear too. 

From Madagascar?

The layer of shell that you refer to as 'opalized' is the nacreous layer of the shell, aragonite and conchiolin and found in many molluscs.

Yes, both came from Madagascar.

And what you have in both are polished calcitized steinkerns of the phragmocones.

Thanks for the info.  I just went down a rabbit hole of what is a stinkern vs a mold vs a cast.
