I didn't need to more the vase... I think the ring was adjacent and could be picked up without disturbing the vase. HOWEVER, I'll try to remember to record a screen shot or two next time I'm down there in the Moira Prison... By the way, I found that accessing the prison from behind the staircase is MUCH safer and easier than trying to go down to the right through the thick of a bunch of Zombies...

do you mean you were able to look down inside the vase and find it, or you mean the vase was on top of it and you somehow moved the vase out of the way?

The Child's Memory ring seems to be on the floor at the base of a vase, not inside... I didn't need to break the vase to find it...
