This is the sterling silver pendant designed after the classic Celtic trinity knot and accented with marcasite stones. One of Ireland’s most iconic symbols, the Celtic trinity knot has decorated Irish art since the early Middle Ages and symbolize the Holy Trinity, eternal life, and enduring love with no beginning or end. The pendant is embellished with marcasite, a light crystal with a metallic finish that provides a unique sparkle. The pendant also comes with an 18" sterling silver chain and is hallmarked in Dublin Castle—guaranteeing its Irish authenticity. Pendant 13mm L x 13mm W.
