I lost my Engagement Ring -in Dublin at Mcdonalds area location or the HOP on HOP Off Tourist Welcome Center Area

So glad I found this site. September 2019 I was in Dublin. I lost a size 9 14K WHITE gold Engagement Ring. It has a Halo of diamonds on top and a triple shank wide band consisting of about 35 diamonds. The center princess diamond of 4 triangular diamonds giving the appearance of 1 diamond. It means a lot to me as I never was able to have a proper ring or a renewal of vows for our wedding 42 years now, and my husband saved for the purchase of the ring and so it is sentimental. It was one of a kind. Somebody is wearing it or has it in their possession. Please I lost it at the Tourist Center where there is HOP on and Hop Off buses. There is an Asian fellow who was giving out pamphlets of sight seeing, and I felt my hand tugged, but never thought of it. Also I was in the McDonalds in the city as well. I never went anywhere else.
