Finally got to 7/16" so here's some 10mm stuff I have:
-Single-flare aqua Gorilla Glass colorfronts: http://www.bodyartforms.com/productdetails.asp?keywords=gorilla+glass+aqua&button=Search&RecordDisplay=&Filter=Yes&ProductID=7605&index=8
-Single-flare light blue titanium eyelets
-Single-flare acrylic sugar skull plugs (they say they're glow in the dark but I've never worn them so I'm not sure how well they glow): http://www.bodyartforms.com/productdetails.asp?keywords=acrylic+skull&button=Search&RecordDisplay=&Filter=Yes&ProductID=9767&index=6
I also have a pair of "sea blue pearl" earskins with a 1/4" wearable if I can find them. If you're interested I'll look, I think they're in a pocket of a purse but I'm not sure which one.
