Alan Ardiff 'little flower' lost between blanchardstown and Dublin City centre

I lost my Alan Ardiff 'little flower' necklace. It is a silver chain with a circular pendant with a silver little flower set in the centre of the pendant on a black background. I lost it sometime between the morning of April 2nd and the afternoon of April 4th I travelled on the 39A into and out of town from Ongar and walked in the area of D'Olier street and the grounds of trinity. If found I would greatly appreciate its return as it is a very sentimental piece of jewellery which I wear all of the time. Thank you.
