Over her decade as a royal, Duchess Kate Middleton has worn many exquisite pieces of jewelry but has only worn four tiaras. This restriction is said to be due to strict royal regulations. Although the number is limited, the design of these four pieces is still captivating with their stunning beauty.

The first tiara that Duchess Kate wore was called the Cartier Halo, which helped to enhance her look on her big day. The famous jewelry brand Cartier crafted this tiara in 1936, with 739 brilliant-cut diamonds and 149 sparkling baguette diamonds.

The Cartier Halo is a precious piece in the collection of Queen Elizabeth II. Before Duchess Kate, this tiara was worn by Queen Elizabeth, Princess Margaret and Princess Anne on various occasions.

In 2022, Princess Kate Middleton wore the Lotus tiara at a gala at Buckingham Palace. Wearing a long-sleeved sequin dress by Jenny Packham, the Princess of Wales completed her elegant look with Queen Elizabeth II earrings and the intricately designed Lotus Crown, a favourite of Princess Margaret.

Previously, in 2015, the Princess of Wales chose this tiara for a state banquet honoring the President of China.

The Duchess of Kate's most frequently worn tiara is the Lover's Knot Tiara, which was also a favourite of Princess Diana. She first appeared wearing it at the annual diplomatic banquet in 2015. Since then, the Princess of Wales has worn the royal jewellery to the same event for three consecutive years.

In addition, the Duchess of Kate has chosen to wear this stunning tiara for formal events and receptions at Buckingham Palace. In 2022, she wore the Lover's Knot tiara at her first state dinner as Princess of Wales following the death of Queen Elizabeth.

On November 23, the Princess of Wales chose to wear the Strathmore Rose tiara at a banquet welcoming South Korean President Yoon Suk Yeol and First Lady Kim Keon at Buckingham Palace. The tiara had been in storage for more than a century before appearing with Duchess Kate at the aforementioned state dinner. Like other tiaras, the Strathmore Rose has a long history.

Originally a wedding gift from Queen Elizabeth's father in 1923 before she married the Duke of York, the Strathmore Rose was created by jewelers Catchpole & Williams and was inspired by the design of a headdress made of roses.
