If I put rubies In a electric rock tumbler with fine grain sand, will it wreck the rubies ?

The rubies are partly cased in matrix ore rock. They are less than 1" across in size.

No, it won't wreck the rubies. You'll get a Polished Rock and polished rubies. If you want to maximize the value of the stones, you need to dissolve or chip away the matrix. If you like the way it looks and you just want to shine it up some, go ahead.
