You might remember our sponsor Joseph Jewelry from their amazing custom ring options that allowed us to dream up some custom fandom rings. Geek ring fantasies aside, Joseph Jewelry really does rock the custom ring options including some seriously stunning sapphire and colored gemstone options.

With Joseph Jewelry, you can design your own ring and jewelry online with their custom ring builder. While you're able to snag any of their drool-worthy rings from their collections, you're never limited in your imagination.

I've scoured their custom ring archives to see what fabulous rainbow-inspired options we could find to get your brain whirring in a colorful ring direction.
