I posed this question to the group a few weeks ago and the general consensus was don't do it, and I didn't, at least for now. Things I heard was that more often people forgot about one of their shops, and like someone already metioned here It was hard to manage both.
If you plan on making your art prints into your jewelry than it would totally fit! You are going to make the SEO per listing and although total shop elements do come into play, like your shop title and name... you are likely to get found based on your tags and titles more than anything. I've found at least in my shop, listings are viewed based on the search term, and more listing views than shop views or sections -- maybe not the case for everyone but certainly for me.
