The Princess of Wales has become a leading advocate for sustainable jewellery, showcasing a range of necklaces and earrings from companies committed to environmental and ethical practices.
However, she wasn’t the first royal to champion sustainable jewels.
In 2019, Meghan Markle made headlines by endorsing Kimai, an ethical brand renowned for its dazzling lab-grown diamonds.
The duchess, who at the time was notably supporting independent sustainable labels, chose the intricate £630 ‘Felicity’ crawler earrings, set in recycled 18-carat yellow gold.
‘When the pictures went live, we immediately sold out, had hundreds of global press articles which really helped to get our brand name out there – and also spark a conversation around what lab-grown diamonds are,’ Jessica Warch, co-founder of Kimai, recalls.
Meghan’s well-timed appearance came a matter of weeks after the brand launched its website.

During a trip to Nigeria with Prince Harry in May, the royal opted for Kimai’s £695 Semi Hoop earrings, which feature 10 gleaming lab-grown diamonds.
Jessica expressed to MailOnline her gratitude for Meghan’s ongoing support.
She said: ‘We always love to see customers wearing our pieces, it never gets old!
‘It meant so much for Meghan to wear our pieces at such an early and pivotal stage of our business, getting her “seal of approval” really helped to get our brand name out there.
‘We love that she is still a customer of ours years later.’
Kimai emphasises supply chain traceability by using 100 per cent traceable lab-grown diamonds, with jewellery crafted in the founders’ native Antwerp.
The brand has opened a store on London’s Chiltern Street and is looking forward to expanding globally.
‘We always set out to disrupt the diamond industry. Growing up in Antwerp, the diamond centre of the world, we spotted a gap in the market to create a fine jewellery brand for modern women, with transparency at the heart of everything we do,’ Jessica said.
‘We want to democratize diamonds, without compromising on style or quality, and foster a more ethical and transparent approach.’

Last year, sales for sustainable gems achieved a record high, accounting for 10 per cent of all global diamond jewellery sales, up from just 2 per cent in 2018.
Double-digit annual growth is expected to continue, driven by a growing interest from socially-conscious consumers who prioritise high quality and responsible sourcing that minimises environmental impact.
This trend aligns with Kate Middleton’s support for sustainable jewellery brands, as she increasingly selects pieces that reflect these values.
Below are some standout items from her collection.
