Queen Camilla stepped out in full glamour at Windsor Castle as she attended a reception for members of the Diplomatic Corps.
Joining King Charles and Prince William for the annual event, the Queen looked radiant in a white gown, beautifully paired with the Greville Emerald Kokoshnik Tiara.
Leading diamond experts at UK jeweller Steven Stone have taken a closer look at the standout piece, uncovering its fascinating history – and its truly staggering value.
“The Greville Emerald Kokoshnik tiara is made of rose-cut pave diamonds set in platinum and is adorned with six emeralds. The centre features a 93.7-carat cabochon-cut emeralds, which is what makes it so valuable.
We previously estimated the distinctive diamond and emerald headpiece – made by the French jeweller, Boucheron in 1919 – to be worth £10 million, making it the most expensive of all the tiaras we’ve studied.
Wearing emeralds is said to promote friendship, peace, harmony, and domestic bliss by enabling the wearer to both give and receive unconditional love. In ancient Greece and Rome, emerald was said to be the gemstone of the goddess of love, Venus.
Its original owner was Dame Margaret Greville, a famous society hostess who, upon her death, left her jewels to the Queen Mother. When the Queen Mother passed away in 2002, much of that collection, including the Kokoshnik tiara, went to Queen Elizabeth II. In 2018, the late monarch lent it to Princess Eugenie for her wedding day – making it the most extravagant “something borrowed” in royal history.”
