Found 2 silver-coloured rings at Glendalough

Found two rings while walking to Upper Lake in Glendalough this Sunday (30 Sept). Wanted to hand them in to the Visitor Centre but it was closed by the time we got there. The rings don't look expensive but in case they have sentimental value to anyone, I thought I'd post them. If you can describe the two rings in detail (so I know they are yours), I'm happy for you to come pick them up from Dublin, or I can drop them into a post office if you pay for postage.
