The so-called Irish Crown Jewels or State Jewels of Ireland, were created in 1831 for the Sovereign and Grand Master of the Order of St Patrick. The order was established as an Irish equivalent of the English order of the Garter and the Scottish Order of the Thistle.
Delivered to Dublin ‘on the command of His Majesty William IV’ by Rundell & Bridge the regalia contained 394 precious stones of the ‘first water’ taken from the jewels owned by Queen Charlotte and the Order of the Bath star of George III.
