The Jardine Star brooch is one of the Queen’s lesser known jewels, and she chose to wear it to record her annual Christmas speech in 2017.
The diamond brooch matched the Queen’s white gown with silver and gold embroidered flecks.
Shaped like a star and featuring a diamond at its centre and around its exterior, the brooch is set in silver.
It was given to Her Majesty as a gift by Lady Jardine in 1981.
Interestingly, according to The Court Jeweller, it is not known who Lady Jardine was – her identity remains a mystery.
