The rings sound like old seer wedding rings. -Very- nice inscriptions on them. Someone can probably give a better estimate, but I sold one last year with for 25m.
With Valentine's Day coming up and the mention of EM weddings, might be a good time to find a buyer and possibly make top gold for them. It has not been mentioned, to the best of my knowledge, if the EMs will be giving out rings with the ceremonies or not. If they aren't of course their value is safe. If they do and they are similar to yours, the price will drop. That's the one thing that really bites about rares collecting. Your item can drop over night in value like a rock if EA puts in something that mirrors it. *laughs*
Good luck with them!
P.S. Aibel is right. Those two items are new haven skill quest items. They still have some value and can sell from 5k-50k depending on buyer/shard.
