New TARDIS ring

I've put a new style of TARDIS ring in the Etsy store, one that has a plastic gem in it for the light since the print orientation would make that overhang. I like the way it looks and it's subtle enough for daily wear. However I was thinking it might look better in metal with a real gem so I modified it for shapeways. not 100% sure it will work as a setting since I've never done this sort of thing, but I followed Mikhail Rachinskiy's tutorial so I should be okay, right?
