Lost golden pendant in Dublin 4

I have lost something extremely precious to me. Last Thursday evening 14ty feb I lost a gold pendant. My pendant is one of 6 that my family had commissioned after my brother drowned in a sailing accident. The pendant has some of his ashes enclosed in it. I feel totally lost without it, feel anxious not knowing where it is and sick at the thought that someone else might have it and not know or respect its meaning and importance. I am getting married in 6 weeks and am devastated at the thought of not having this pendant on me on the day. I lost it either around Fitzwilliam square/ Pembroke street or around Spar on Barrow street area. If anyone has it/knows anything about it please email [email protected] I will reward generously for its return. Thanks Triona
