With Kate Middleton dazzling at the 2022 Earthshot Prize awards ceremony in Boston, I thought you might be interested in the below information about the emerald and diamond choker that she was wearing.

The Princess of Wales graced the green carpet at the 2022 Earthshot Prize awards ceremony in a rented off-the-shoulder gown from the brand Solace London, though it was her eye-catching emerald and diamond choker – previously worn by her late mother-in-law, Princess Diana – that everybody had their eyes on.

Diamond specialists at UK retailer Steven Stone have shared everything we know about the choker – including how much the sentimental piece is worth and how it labelled Princess Diana a trendsetter back in 1997.

The art deco diamond-and-emerald choker belonged to Princess Diana, who received it as a wedding gift from Queen Elizabeth II
The diamonds look to be around 10 carats each – they’re old cut stones, which makes them even more valuable
Whilst designed to be worn as a necklace, Princess Diana often worn the sensational choker as a headband
Our experts estimate it to be worth anything from £10,000,000 to £15,000,000,000
Maxwell Stone commented: “When it came to wearing jewellery, Princess Diana knew exactly how to make each piece stand out. From remodelling brooches into necklaces, to wearing chokers as headbands, she set some huge trends and was always showcasing her jewels in unique ways.

Whether it was an accident or not, wearing the Dehli Durbar Emerald Choker as a headpiece was a wonderful choice by the Princess and certainly supported her trendsetter reputation.

The diamonds in this piece alone are magnificent, looking to be around 10 carats each. They are old cut stones, which makes them even more valuable. While it’s so difficult to put a value on a piece like this that has such a rich history – even more so now that Kate has worn it – it could be worth from £10,000,000 to £15,000,000,000.”
