one site that did and wound up spending like 30 minutes customizing a Starfleet Academy class ring. I'd never buy it for myself, because it'd cost like $120, but it was fun to play around with.
Then I got to wondering though, would there be a market for this? Now that being a nerd about something isn't a giant social stigma you'd think companies would capitalize on it, but they've yet to do so. Would it be illegal for me (or anyone unaffiliated really) to profit from this sort of market?
Like, were I to make Starfleet and Hogwarts class rings and sell them, would that be copyright infringement? I'm not considering it seriously, obviously, but it makes me wonder. Were I Urban Outfitters I'd probably be fine, of course, but as just a sole entity would this be acceptable?
