A ring enchanted by the orange eye of Kalameet, the bringer of calamity.
Owning this is a mark of true grit in battle.
(Since printing in multiple colors/materials isn't an option, I recommend painting the eye in with nail polish! Seems kind of a hack method but it's very easy to do and comes out very, very nicely.)
Other sizes available on request. Prices may slightly vary with larger ring sizes, to account for the material cost.
