Absolute Ring Event

Thank you.

Next experiment for someone brave to try: put your +11 ring in storage and try to get a 12th stamp (and hope that gives you an extra day you could miss on a subsequent ring, and still get the Absolute one).

No problem. But to answer your second part there I can already tell you it won't work. Once you've been awarded 11 stamps, Gaga won't even let you get a new ring, his dialog is completely different. Doesn't have any of the ring options, just says something like "You have already upgraded a ring 11 times."
