A Savvy or Savvier Selling Store Question

Hi!

There are a few items which I'm wondering if they can be sold using either the savvy seller set or the savvier seller mod. They are:

-Uncut or Cut Gems
-Smelted or Raw Metals
-Paintings created by artistic Sims
-Mounted Fish

These things would be a part of the Home Accent section of a department store I'm working on creating. If there are any known issues with selling any of the items please let me know.

Thanks
