Lost silver moonstone necklace in Dublin 11/9/2012

I lost a necklace of small moonstones connected by silver chain with one moonstone dropping down in the centre. Possibly lost in Baggot Street or Ranelagh or in a taxi on the way from one to the other. I had to remove it for an x-ray in baggot street, placed in safe in my inside pocket and never got the chance to put it back on before realising it was missing. May have fallen out of pocket whilst paying taxi driver?? Please if you have found it return it to me as it is hugely sentimental!!! I will of course offer a significant reward.
