I don't think I know any Brothers who split their SR degrees out enough to have time to receive a 14th degree ring before they made it all the way through. I've read that European jurisdictions still do individual degrees so it can take them years, but the US jurisdictions switched to classes going on a century ago.
You do now. My valley (Rochester Minnesota) doesn't do "reunions." We confer the degrees over ten months, from September through June, each year. We even have a little ceremony to present the 14° rings to those who ordered one when they petitioned at the start of the year. For example, this year they got the 14° in December, and have their rings (and the right to vote on business matters, since all business of the Valley is conducted in the Lodge of Perfection) for six months before getting the 32° in June.
In the Southern Jurisdiction (yes, Minnesota is Southern Jurisdiction) the official position on 32° rings is that they have no problem with members wearing them, they just aren't recognized as "official," so there is no standardization.
I have no knowledge of the ring rules of the Northern Masonic Jurisdiction, nor of PHA Scottish Rite.
