This is a D10 die engagement ring. It was custom made, but doesn't contain any precious stones so it was probably still significantly cheaper than a traditional engagement ring. Because what better way to symbolize a relationship than PURE CHANCE. Rolling for true love -- come on, daddy needs a ten! *rolls* A two?! F***, we don't even like each other do we?
Thanks to chichi, who agrees if diamonds are a girl's best friend then dice are probably frenemies.
