The shamrock in these enamel stud earrings is an instantly recognisable emblem of the Emerald Isle. The shamrock is said it was plucked from the land by St Patrick to explain his belief in the Trinity, and many believe that wearing this spring of green will keep them safe from harm. These enamel stud earrings are therefore a great way to wear this good luck charm everyday. They have been Irish hallmarked in Dublin Castle.
