Perhaps it's Solaire's remains in the Chosen Undead's time. If Solaire is truly the descendant of the Firstborn, he'd probably have that ring at some point.

Solaire pretty much says that you're time and his are on two different levels. Perhaps the Solaire we meet in Anor Londo is from the past, and the remains found in Anor Londo are his, perhaps in an attempt to claim the Sunlight Blade, the miracle of his ancestor.

I personally don't believe this is the case, but it's still a theory.
