Maybe someone else knows more?
English fruit cakes aren't all that much like American fruit cakes; they're a lot less sweet and tend to contain dried fruit rather than candied fruit. They do keep a long time, but I don't know that it'd be safe to eat after that long. I should think it'd have been fossilised by now!
I think slices of the royal wedding cakes would be given as keepsakes to family members, friends, and maybe trusted members of staff, so it's possible that there were a fair number of these pieces of cake in circulation, and not just among close family. I'm not sure why they'd have bought their cake boxes from the jeweller rather than the caterer, but it might not have been the original box.
