|The Irish Silver Spiral Brooch|
On her state visit to the Republic of Ireland in 2011, the Queen was presented with this brooch by President Mary McAleese. Both the brooch and the matching cufflinks given to the Duke of Edinburgh were created by goldsmith Declan Killen. The brooch is made of sterling silver and has ten disks with spiral designs inspired by motifs from the Newgrange monument.
