what gem stones can be tumble polished together?

Question

i have a few handfulls of rubies emeralds garnets and sapphires and am wondering if they can be tumble polished

Answer 1

These precious gems would not normally be tumble polished at all, much less together. They would be carefully shaped for maximum reflection. Rubies and emeralds are normally facetted like a diamond. Sapphires are ground round and oval, especially (only?) star sapphires. If you really have a couple of handfuls and this is not a tongue in cheek the stones should have a value in at least the tens of thousands if not hundreds of thousands of dollars in value.
