Lost grandmothers part of ring

More than happy to offer a reward or buy you pints if found. On Friday evening, I lost a really special part of my grandmother’s ring, and I’m absolutely gutted. It’s the inside piece of the ring—an orange stone with a little white cameo face in the middle (I’ll attach a picture). I was having drinks in The Exchequer in Ranelagh and realised it was gone when I was heading home. I got the 15 bus from Rathmines outside Blackbird to Marino, and checked bramstoker park and since then I’ve tried retracing my steps, but no joy. This ring means so much to me it’s one of those pieces that you just feel connected to. If by any chance someone spots it on the street, on the bus, or anywhere in between, I’d be over the moon to hear from you. Thanks so much for reading this and here’s hoping for a bit of luck and kindness. You’d really make my day! Cheers!
