Corian is a real good base.
All the porous rocks that are cut and de burred work the best sonically. Coral, volcanic, manmade.
The metamorphic/igneous rocks will ring like a bell. Granite, basite even concrete, UNLESS its fluffed (add a lot of air to the mix) it will ring.
Sedimentary rock like Caliche, are pretty quiet, when sliced.
Personally I like the way it looks in a cross section.. Almost burl like.
