While a ring on a finger is a nice giveaway, knowing the truth of a woman's (or man's) marital status might be of benefit. After all, those rings can be removed when need arises.
I plan to introduce these at the start of a Caleon episode, with the symbology in an arcane and totally made up code the wearer will not understand. I'm sure seeing strange symbols over every head in town will result in much confusion and fun for all. Then again, they might firgure it out after only a few minutes of reasoning. I plan to use symbols for Unattached, Dating, Engaged, In Love, Unrequited Love, Married, Happily Married, Divorced and probably a few others. This way, the PCs will have to ask a lot of questions to figure out the code.
