Irish silversmith Michael Hilliar first designed the History of Ireland jewellery collection in 1970, drawing inspiration from the 5th-century carvings adorning Ireland's Celtic high crosses. This beloved collection has now been relaunched in 2025, spotlighting its original symbolic artistry once again. Each piece in the History of Ireland jewellery collection is engraved with 12 symbols representing some of the most important eras in Irish history.
