Silver plate celtic cross necklace. It's a fairly small cross- about 2cm long and 1.5cm at the widest point across. Simple, Irish, pretty and very reasonably priced. Comes in purple display box.
Good Craic stocks a wide range of Irish souvenirs including many items you may not see elsewhere. I cherry pick the very coolest items from the various suppliers. The shop is eclectic and fun and definitely worth a visit if you are in the Mourne area.
