When Princess Catherine graced the Earthshot Prize ceremonies, she didn’t just attend; she made a statement that resonated across fashion and royal circles alike.

Her outfit was nothing short of spectacular, featuring a vibrant green dress from Soleil’s London that radiated energy and sophistication.

The deep hue of the gown perfectly complemented her natural poise, making her a standout figure at the prestigious event.

However, it was the stunning jewelry she chose that truly captivated the audience.

Catherine adorned her ensemble with a magnificent emerald choker, famously known as the Queen Mary Emerald Necklace.

This exquisite piece carries a rich history, having been a favorite of Princess Diana.

Its estimated value of $20 million adds an astounding layer of significance to the occasion, making it a remarkable choice for such a high-profile event.

Diana often paired this luxurious necklace with an array of dazzling tiaras, further solidifying its status as one of her signature pieces.

By donning it, Catherine not only paid homage to her late mother-in-law but also showcased her growing appreciation for the royal jewels that have been cherished through generations.

It was a moment that beautifully intertwined the past with the present.

While the emerald choker certainly took center stage, it’s just one gem in Catherine’s impressive jewelry collection.

The Princess of Wales has consistently demonstrated her refined taste, boasting a treasure trove of some of the most iconic pieces in the royal vault.

One notable item is the Cartier Halo Tiara, which she wore on her wedding day to Prince William.

This diadem, adorned with 739 brilliant-cut diamonds, signifies her journey from a commoner to a princess.

The tiara’s historical roots run deep, having been gifted to Queen Elizabeth by her grandmother.

Today, its estimated worth stands at around $1.5 million, a testament to both its craftsmanship and royal lineage.

It’s not just a beautiful accessory; it symbolizes Catherine’s place within the royal family.

Another jewel that highlights Catherine’s extraordinary collection is the Nizam of Hyderabad Bib Necklace.

This breathtaking piece features 50 dazzling diamonds arranged in an intricate pattern, all set in platinum and designed by Cartier.

With an estimated value exceeding $80 million, it ranks among the most expensive items in the royal collection, showcasing the opulence of royal gifts.

Catherine’s engagement ring, originally worn by Princess Diana, is perhaps the most famous piece in her jewelry box.

This iconic sapphire ring, surrounded by a halo of diamonds, represents not only her bond with William but also a profound connection to her late mother-in-law.

Its value transcends mere monetary worth, embodying a rich family legacy.

Beyond these show-stopping pieces, Catherine also treasures a more understated yet equally valuable collection.

Her diamond carriage studs and matching chain, with their delicate floral design, are valued at over $8,500.

The first time she wore them was during Princess Charlotte’s christening in July 2015, marking them as enduring symbols of elegance and familial love.

Among her favorites are morganite and diamond ear cuffs, featuring large pear-shaped studs enveloped in sparkling diamonds.

Worn at Pippa Middleton and James Matthews’ wedding, these earrings reflect a softer side of royal glamour.

Their delicate pink tones set in yellow gold exude a timeless beauty, with an estimated value of over $5,000.

Catherine’s choices in jewelry not only highlight her exquisite taste but also serve as a bridge connecting her to the storied past of the British royal family.

Each piece tells a story, celebrating both heritage and personal style.

As she continues to evolve in her role, her affinity for these remarkable jewels only deepens, making every appearance a captivating blend of history and modern elegance.
