Stepping into the Monégasque royal family over a decade ago, Charlene Wittstock transformed from a sporty Olympian swimmer to the elegant Her Serene Highness Princess Charlene of Monaco . She follows her mother-in-law Grace Kelly, bringing vitality and glamour to Monaco with her classy style every time she steps out. But beyond her chic outfits, diamond sparkles are obviously a dazzling aspect of her style too – and she has called on some truly prestigious jewellery brands to ensure that she shines at important events over the years. So who are they? 1. Cartier View this post on Instagram A post shared by @hshprincealbertii Cartier is obviously one of Charlene’s favourite names. A particularly striking moment was when she donned the white and yellow diamond L’Odyssée de Cartier at the 2016 Monte Carlo TV Festival. The collection was inspired by an imaginary journey through the Old World, from Africa to Asia, according to the brand. It has pear-shaped diamonds totalling about 20 carats, worth nearly US$4.7 million, estimated by Luxury Finds. 7 handbags named after famous female icons, from Princess Diana to Selena Gomez Another time, at the 2015 Red Cross Ball, a diamond bracelet from Cartier’s iconic Panthère jewels collection glittered on her wrist. It was a 18k pink gold set with 1,302 brilliant-cut diamonds totalling 30.28 carats, worth US$236,000, according to The Royal Couturier. Charlene has also opted for several pricey earrings from the jeweller, such as a US$192,000 pair of Panthère de Cartier earrings with diamonds, sapphires and onyx that she wore at the 2016 Princess Grace Awards in New York, or another diamond and pearl pair at the 2017 Laureus World Sports Awards that Christie’s estimated to be worth US$62,000. 2. Dior When Charlene appears on the front cover of style publications, Dior is her jewellery maison of choice. For instance, on Point de Vue’s January 2021 issue, she put on the Mise en Dior pearl resin necklace and an elegant white silk jumpsuit while posing at the Prince’s Palace. Rihanna also wore the piece at Lanvin’s autumn 2014 show.

She has often been spotted sporting them, whether visiting the Monaco Red Cross headquarters in November 2016 or at a rugby match between England and South Africa in the same year. For a photo shoot for Vanity Fair Italia and Gala magazine, she also glammed up in a black Dior jumper and flower earrings from Dior’s Milly Sous la Neige collection that The Royal Couturier estimated to cost about US$5,000.

It features a massive three-carat, pear-cut diamond flanked by smaller diamonds in triangle arrangements, costing nearly US$70,000, according to British media. She has often sported fine pieces by the Italian jewellery house since then, from the Brevis white gold and diamond asymmetrical choker at the 2020 Monte-Carlo Gala, to her pair of gold flower earrings that she wore at the 2018 Monte-Carlo TV Festival, the 2019 Red Cross Ball Gala 2019 and, most recently, the 2022 Monte-Carlo Fashion Week Awards. 4. Graff View this post on Instagram A post shared by @hshprincealbertii Charlene clearly has a passion for earrings – Graff’s pieces, in particular. She has shown off a variety of delicate drop earrings by the British jeweller over the years. One of the most impressive was the 30.57-carat diamond hoop earrings at the 2019 Monte-Carlo Film Festival. Other Graff diamond earrings that she’s favoured include a pair comprising 43 carats of aquamarines and 3.15 carats of diamonds at the 2013 Monaco Red Cross Ball Gala, the “waterfall earrings” at the 2012 Academy Awards, and the round- and pear-shaped drop earrings at the 2014 Red Cross Gala, which she paired with with Graff’s flower-motif Alice headband. 7 of Meghan Markle most expensive jewellery pieces, from Cartier to Asprey She also appreciates red rubies. She’s shown up with an oval-shaped drop pair matching with her beaded dress at the Princess Grace Awards 2015, another drop pair at the 2015 Monte-Carlo TV Festival, and one with 20 carats of rubies and 11 carats of diamonds at the National Day celebrations 2019. Each of them is estimated to be worth up to US$700,000, per The Royal Couturier. 5. Van Cleef & Arpels Van Cleef & Arpels has been regarded as the “official supplier” to the Principality of Monaco since 1956 when it designed a pearl parure for Princess Grace. So it came as no surprise when Prince Albert of Monaco asked the Parisian jeweller to make a special wedding gift for his bride in 2011. The set honours Charlene’s swimming career: dubbed Ocean, it’s designed to look like sea waves and includes a tiara, a necklace and a pair of earrings. The tiara and necklace have some 1,200 stones each, of which 850 are diamonds embellished with turquoises. She appeared wearing the tiara on the front cover of Hola! magazine in April 2014, the necklace at the 2011 Red Cross Ball and Charity Foundation AI IA Gala in 2020 in Tbilisi, and the earrings at the 2014 Rose Ball and a Van Cleef & Arpels event in 2012. Most recently, she attended the 2022 Red Cross Ball with a new Van Cleef & Arpels’ Envol Butterfly necklace and bracelet in white gold and diamonds. The bracelet costs around US$125,000, per British media. Escape to the African bush like Prince Harry: 5 luxury getaways to try 6. Tabbah Tabbah is another of Charlene’s go-tos for big events. For her civil wedding ceremony in 2011, she wore diamond stud earrings from the Lebanese jeweller, pairing them with an unusual strapless blue jumpsuit and blazer, per The Court Jeweller. She wore the earrings again for her 11th wedding anniversary.

She just removed the blazer and earrings, adding a striking necklace by the same brand. Known as the Infinite Cascade Necklace, the piece is made of 18k gold and 1,237 diamonds weighing a total of 56.67 carats, and six white pearls. It costs between US$300,000 and US$500,000, Ocean Draw estimated. Want more stories like this? Follow STYLE on Facebook , Instagram , YouTube and Twitter .
