It’s the classic question mark icon from the Super Mario Bros. games. I’m not sure if its classy enough to be used to propose to someone, but it could come in handy in a fight. And you know how often us geeks get into fisticuffs right?
Each sterling silver question mark ring is made to order and it takes about 12-15 business days to be made.
You can order the ring from SmilingSilverSmith for $49 (USD). They also make other punctuation rings, in case you’re more of a Metal Gear fan.
