Look @ pics of her from the engagement photo session w/her arm thru William's. Her hand looks old there too. That being said it's still a great ring & if you don't recognize it you've been living under a rock. For a LOOOOONG time.
i have a ring just like that one...
Everyone's hands look like that zoomed in. They probably brightened up to pic too to make the ring look sparkler so that probably makes the hand look a little funny.
