Nenya or the Elessar?

Fair Lórien certainly was. However, in the scheme of things in Middle-earth it was unnatural. A pocket of timelesseness had been created in a world in which time was not static. I don't believe that state could not have endured indefinitely, regardless of whether the One perished, or remained unfound. The Elves were ultimately doomed to fade if they did not return to the Undying Lands, and neither Nenya, nor the other two of the Elven Rings would have been able to stop that. I think Galadriel and Elrond knew that their actions with Nenya and Vilya were only temporary.
