Yvonne Bolger Earrings Collection Sterling Silver Stud Earrings With A Round Circular Shape & A Heart Centre. These Earrings are part of my “Love Knot” Collection which is my modern interpretation of the Ancient Celtic Knot. The Love Knot symbolises love, loyalty and friendship and is inspired by the Celtic Myths and Legends which resonate so deeply here in Ireland’s Ancient East. Each Stud Earring is 13mm Wide x 14mm Long approx. with a Butterfly/Push Back on Post. Very slight variations may arise due to the hand crafting of each individual piece. All pieces are Hallmarked by the Irish Assay Office.
