quality of polish

It's unclear whether you mean the quality of the polishing action (how well the item was polished) or the quality of the polish substance used. However if you mean either of these only option 1 is correct.

In option 2 "polished quality" can only refer to the attribute of being polished, or the fact that the quality of end 1 has been " polished" (artificially increased). It cannot refer to how well end 1 was polished or the polish substance.
