Kate Middleton wore earrings from London-based sustainable jewellers for Wimbledon day out - and they're more affordable than you might think

Kate Middleton made a very fashionable return to public life once more on Sunday, joining her daughter Princess Charlotte for a day out at Wimbledon tennis. 

The royal, 42, has taken time out of the spotlight in recent months as she focuses on her recovery from cancer treatment. 

The Princess of Wales looked stunning as she attended the men's finals tournament, before presenting winner Spaniard Carlos Alcaraz with the trophy. 

Kate was as radiant as ever in a purple £1,295 bespoke dress from Safiyaa - and even added a pair of brand new earrings for the occasion. 

She opted for the sterling silver and gold Sabine Hoops by British independent jeweller By Pariah - a London-based sustainable brand.

The sleek but chunky hoop design is a fashionable look, and added a glamorous element to her simple but elegant attire. 

The princess is known to love a modern brand with a story, and the earrings are somewhat more affordable than items she usually wears. 

The Sabine Hoops retail at £400, but also offer a smaller version for £280 and silver alternatives for £300 and £300 - and a clip-on option. 

The pieces are stocked at Liberty, Net-A-Porter and Harvey Nichols, where they rapidly sold out following being worn by the Princess, according to Woman and Home magazine. 

'I think they’re so popular because they’re so easy but also make a statement,' founder Sophie Howard told Harpers Bazaar.

'They dress up an outfit but in a cool, effortless way. They’re a unique alternative to your classic gold hoop.' 

She added: [It feels] completely surreal to be honest but so special. I am so proud of our team and am deeply honoured and grateful for Kate’s support.' 

The brand is beloved by A-listers, with Hailey Bieber also wearing the Sabine Hoops, while Katie Holmes and Florence Pugh have worn the Large Drop Earrings.

Even Michelle Obama has shown her love for the brand, opting for the orbit rings in citrine and green amethyst. 

The brand's name itself is inspired by an article in National Geographic Magazine, describing the Pariah parts of the Caribbean. 

It oozes sustainability and luxury, with all pieces made from 100 per cent recycled gold and silver, using gemstones in their untreated form, and recycling 80 per cent of water usage back into the manufacturing process. 

'Above all, our collections are designed and made to be worn and loved for as long as possible,' By Pariah's website states.

'We believe in seasonless pieces that can be passed down from generation to generation, that are durable and transcend time.' 

The brand's celebrity cult following was a good fit for Kate's outing to Wimbledon, as she was joined in the royal box by the likes of A-listers Tom Cruise and Benedict Cumberbatch.

Other details in the Princess of Wales's look included her favourite green-and-purple bow for the occasion.

Since 2017, the mother-of-three has donned the elegant brooch - which features the tournament's iconic colours - every time she has visited Wimbledon.

Kate debuted her green-and-purple bow back in 2017 - when she paired it with a white short-sleeved dress.

The future Queen has since worn it for her annual appearances at the grand slam event since then.

Last year, the Princess of Wales donned the prestigious accessory on the last day of the competition with her elegant emerald green frock by Roland Mouret.

In 2022 she pinned it to her chest alongside her Alessandra Rich navy dress polka dot dress and also to her bright yellow Roksanda gown. 

More than just a mere accessory, the Princess' go-to Wimbledon brooch is actually a symbol of royal patronage, gifted to her from the Queen Elizabeth II

Kate took over the role of patron in 2016 from the late Queen who had held the position for 64 years. 

The accessory is worn by members of the Committee of Management during the Fortnight – the Main Board of the AELTC and representatives of the LTA. It signifies their responsibilities as the Committee governing the tournament.

The Patron has always traditionally been given a Committee bow in recognition of her role, which is why the Duchess has chosen to wear it when visiting The Championships.

Other individuals also given an honorary Committee bow are the Chief Executive.

Kate and Charlotte, nine, and her mother, the Princess of Wales, 42, arrived to take their seats at the Royal Box on the Centre Court, the pair were met with a standing ovation and applause.

The duo and Kate's sister, Pippa Middleton, saw the reigning champion, Carlos Alcaraz take on veteran Novak Djokovic, winning in three sets. 

Kate and Charlotte, nine, spoke to the tennis player Alcaraz off the court and revealed she had been watching his performance at home.

The mother-of-three, who has stepped away from public royal duties while undergoing cancer treatment, said: 'This is Charlotte, [she was] cheering you on. You had everything crossed.

Alcaraz, who was dressed in all-white and holding his trophy, replied: 'Nice to meet you.' 

Kate then said: 'We've watched a lot on telly, so it's great to finally get to meet you,' before repeating herself as the athlete was struggling to hear her. 

A star-struck Charlotte looked slightly shy as she stood next to Kate and smiled at Alcaraz during their conversation, as her aunt Pippa stood behind the pair and grinned at the interaction.  

Before passing the trophy to Alcaraz earlier on, Kate commiserated and shook the hand of runner-up Novak Djokovic.

Dressed in a £1295 bespoke dress from Safiyaa, the royal was greeted with a standing ovation as she headed into the Royal Box at Wimbledon earlier in the day.

Before the mother-daughter duo took their seats in the Royal Box, they met with female tennis stars, including 21-year-old Emma Radacanu, who all presented Kate with a bouquet of flowers

Charlotte grinned from ear to ear as she met with the tennis star, who sadly saw her Wimbledon dream crushed on Centre Court by New Zealand qualifier Lulu Sun last week.

Kate and Charlotte were also greeted by Sonay Kartal, Lily Miyazaki, Lucy Shuker and Flora Johnson as they arrived on the players' lawn at Wimbledon before entering Centre Court.

Charlotte gave wheelchair tennis player Shuker a 'pinky promise' that she would try the sport alongside her mother.

Kate was also introduced to Raducanu, who was knocked out in the fourth round of this year's championships, telling her: 'It was so hard to see you go out.'

US Open winner Raducanu said it was 'amazing' to have the support of the princess and 'see her here looking so healthy and happy'.

The daughter of the Prince and Princess of Wales, who sported a £70 Polka Dot dress from Guess, was thrilled to meet the tennis star, and was photographed smiling ear to ear in her presence.

The mother and daughter then met the 'Work at Wimbledon' programme which supports young people from a range of backgrounds with roles at the Championships.

Alcaraz now has four Grand Slam trophies with a perfect record in major finals, after his two Wimbledon triumphs, his U.S. Open victory in 2022 and his French Open win last month. Defeat denied Djokovic a 25th Grand Slam title to surpass Margaret Court in the all-time list and also equal Roger Federer's haul of eight men's singles titles at Wimbledon.
