Amazon - Filter search results to eliminate low rated products?

I regularly try to find a type of costume jewelry my daughter likes, and grow frustrated by all the poor quality, ships from Asia products cluttering the search. However, I don't want to eliminate all of those sellers, because some do have decent quality products and are decent sellers. Would such a script be possible?

Amazon lets you sort by review score, but this often puts less relevant items at the top. Using the relevance-based sort, it should be possible to hide items in a page based on information contained within those items. However, Amazon has many different page layouts (for example, a long list, a set of tiles, etc.), so the script will need to be able to recognize and modify the ones you generally see.

It's possible this exists, but I didn't see it in a search.
