Much of the time when men eschew wedding bands, people assume they're up to no good.
However, that's not the story with the Duke of Cambridge, whose choice to not wear his wedding ring is - surprise, surprise - a part of traditional aristocratic etiquette.
In fact, the history of male wedding rings doesn't go back that far, only to World War II, Harper's Bazaar reports, when soldiers wore them as reminders of their home life. Women's wedding bands, though, originate from Egyptian times.
The royal family has never fully adopted the custom of wedding bands for men. Prince Charles wears his ring, yet William and Prince Philip choose not to. This is the norm for British high society, though.
"It is not unusual at all for men from the upper sets in Britain to shun wearing a wedding band," etiquette expert William Hanson told Harper's Bazaar.
"This is not because of any intentions that they may wish to play away from home once married, but because it was traditionally not the done thing for gentlemen to wear jewellery.
"Years ago, this even included watches, but even hardened snobs have relaxed on that front."
Well, we're glad they're at least allowed timepieces!
"Not wearing a wedding band is one of those quirky British silent class indicators, like the colour of your shoes on a Thursday or the way you fold your top pocket handkerchief," William noted.
A single exception to the no-jewellery policy exists, though: signet rings.
"The signet ring shows lineage, which is obviously more important than any comparatively trivial romance. Signet rings should only have a family crest on - ones with your initials are treated as a bit suspect," William explained.
We can't imagine how much effort it takes to keep all of these rules straight as a royal!
Now one question remains - will Harry follow tradition and not wear a wedding band or, like Meghan Markle has been, break with custom?
