I wouldn't think you could tell just by looking - after all, it's the
same process - just that the rock tumbler does it rather faster...

Sorry to answer a question with a question, but Why would it matter? It
isn't like beach glass is some long sought after limited commodity. It
isn't particularly rare or collectible in itself to have some forgery value,
so why does it matter? whichever means gives the end result is what I would
think would be important, and how it is used even more so.

to answer your question, carbon dating could give you a precise age of the
material, but don't know that it is quite worth it.

Only if it's really old and was originally part of a living thing. And
even then, "precise" is a relative term. Wikipedia seems to say that
for samples less than 10,000 years old, dating to within 40 years either
way is considered reasonable.
