These sterling silver black Tree Drop Earrings are from the Trees Collection by Breda Haugh and are inspired by forged spiral tree like designs on bread irons that were used at Irish kitchen hearths. The "black" silver is sterling silver which has been coloured by oxidation. It may fade a bit over time which gives a lovely effect. It is perfectly safe and does not stain. It is used here to reflect the black of the forged iron artefacts in the Museum's collections. Original examples of the work of the blacksmith are to be seen at the National Museum of Ireland - Decorative Arts & History and at National Museum of Ireland - Country Life. Assayed at Dublin Castle. Exclusive to the National Museum of Ireland. Dimensions: W 25mm (at widest) H 24mm (incl loop).
