If shell then it is a carbonate compound which should dissolve is a weak acid.
Maybe that CLR stuff will work.

I thought about that...but I'd worry about the opal...I'd think that the CLR would dissolve that as well.

Possible.
Here is link to Opal composition, which is silica:

And here is link to CLR MSDS which lists the active ingredients:

A little additional research should give you the answer.
