"The razor-sharp diamond point is set into the ring so it can't get knocked out when you smash someone's face in, and the edges of the ring are really soft so it won't cut into your skin during the pounding. It's romantic because it means, "Will you marry me?" but it also means, "I can't always be there to protect you so if some jerk won't stop bothering you, puncture him with this." The diamond sharp edge will also cut skin down to the bone (with a minimum 1 karat stone - but the larger the better). Or it may simply be used to tag hard surfaces, like cars and windows for S.O.S. messages or that last will and estimate when pen or paper (or lawyers) aren't conveniently around."
