Meghan wears Princess Diana's diamond bracelet

Meghan, the Duchess of Sussex, paid tribute to Princess Diana by wearing a piece of her jewelry during a tell-all interview with Oprah Winfrey.

In her and Prince Harry's first major TV appearance since leaving their roles as senior royals, Meghan can be seen wearing the sparkling diamond tennis bracelet once owned by her late mother-in-law.

Reportedly by French luxury brand Cartier, the item was worn in public by Diana several times prior to her death. Harry is thought to have taken stones from the very same bracelet to produce the engagement ring he proposed to Megan within 2017.

It's not the first time that Meghan has worn the bracelet, having appeared to do so during a royal tour in 2018. She also wore a ring owned by Harry's mother before the pair's wedding reception that same year.

In the wide-ranging interview, which aired Sunday evening on CBS, Prince Harry told Winfrey that Princess Diana would have been "very sad" about the couple's decision to step back from the royal family.

"I think she would feel very angry with how this has panned out, and very sad. But ultimately, all she'd ever want is for us to be happy," he said, adding that he "felt her presence throughout this whole process."

The topic of jewelry also came up during the two-hour primetime special, with Meghan revealing that the Queen had given her a gift of pearl earrings and a matching necklace on their first joint engagement.

Nods to the past

Wearing Diana's bracelet was one of a number of style statements made during the interview, in which Meghan and Harry addressed their decision to step back from the royal family.

Meghan also sported a gold and aquamarine necklace by British designer Pippa Small, who markets her designs as being hand-crafted and ethically sourced. The Duchess of Sussex, who is expecting the pair's second child -- revealed in the interview to be a girl -- completed the look with earrings by Canadian jeweler Birks.

Speaking to the UK's Town and Country magazine ahead of the couple's CBS interview, Small said Meghan has "really helped highlight ethical fashion and jewelry by choosing brands like ours."

"Meghan has brought awareness to a wider audience as to what ethical means and why it's important," she added.

Meghan has established a reputation for choosing ethical and sustainable brands. She famously wore a gown by Stella McCartney, an early champion of responsible fashion, to her wedding's evening reception.

She was also named 2019's most powerful dresser by the global fashion search platform Lyst, which said that her outfits had sparked, on average, a 216% increase in searches for similar pieces.

The black Armani dress she wore for the Winfrey interview is made entirely from silk and was produced in Italy. The gown, which is embroidered with lotus flowers, is described by the label as "sensuous with a subtle, refined twist."
