This ruby- and diamond-encrusted tiara was a coronation gift to Queen Victoria in 1838 from Sayyid Sa’id, the ruler of Muscat. Muscat had strong trading connections with Qajar Iran, and the tiara was probably made to commission there.

Hidden on the reverse of each teardrop-shaped panel is a colourful enamel scene. There are three designs: a young female figure in Qajar attire, a young male figure in Regency costume and a rose-and-nightingale motif.

Prince Albert later designed a new setting for the tiara, which was carried out in London by the jewellers Kitching & Abud. It is likely that the small seed pearls and upturned drop pearl at the centre were incorporated at this point.
