Princess Irene of the Netherlands will wear a diamond tiara at her wedding to Don Prince Don Carlos of Bourbon-Parma, reports the Associated Press.
The couple will be married next Wednesday in Rome at the basilica of St. Mary Major.
The tiara, valued at $500,000 was given to Irene by Prince Xavier of Bourbon-Parma, her fiancé's father, as a wedding present. It once belonged to Princess Maria de las Nieves of Bourbon-Parma, the wife of Don Alfonso Carlos, a "earlier pretender" to Spain;s throne.
It is "almost certain" that the couple will be "received in audience" by Pope Paul VI shortly after the wedding ceremony."
Princess Irene's parents, Queen Juliana and Prince Bernhard will not be attending their second daughter's wedding.
