Placenticeras prep

[fgiarro]

Hello- I have a Placenticeras meeki specimen in my collection (see attached pic) and I'm curious to know if the iridescence of its shell can be improved in some way, given its condition- Thanks in advance, Fabio

Polishing may improve it, but on the other hand it could make it worse. It probably would depend on the thickness of the nacre and how the play of light works on it. I've done some polishing in my life, but have had no experience with something like this. The nacre looks pretty thin, though, so I would leave it as is unless you know what you're doing.

I agree. 

In the case of this specimen, best left alone, I would say.
