A standout sapphire centre stone surrounded by diamonds ensures this jewellery piece is as eye-catching as it is sentimental. This brooch dates back to the 1840s when it was given to Queen Victoria by her husband-to-be, Prince Albert, on the day before their wedding.

All four subsequent Queens and Queen Consorts have worn this bauble (Queen Alexandra wore it to her coronation in 1902), and it was a favourite of Queen Elizabeth II. She was photographed wearing it on numerous occasions.

Cartier was commissioned to create the Diamond Palm Leaf Brooch for the Queen Mother in 1938. Loose, unused diamonds from her collection were collated and carefully arranged to make this pin, which is named after the Scottish town of Paisley.

The Queen Mother came from a Scottish aristocratic family and Paisley was well-known for its local weavers who would stitch the motif onto shawls during the 19th century. These textiles were shipped all over Asia, and were imported by the East India Company.

When planning what to wear for her platinum anniversary portraits, Queen Elizabeth II decided she would be photographed with her colourful Scarab Brooch.

Designed in yellow gold by Andrew Grima, a society jeweller in the 1960s, this ruby- and diamond-set brooch was a personal present from Her Majesty's husband, Prince Philip, who presented it to her in 1996. How romantic.
