The New-In Section of Kate Middleton's Jewelry Box Will Make You See Dollar Signs

Kate had previously worn a dress by Indian-born Anita Dongre for a visit to Mumbai, later choosing a pair of custom-made pearl earrings by the same designer for a reception celebrating links between the UK and India at Buckingham Palace.

Although Kate had worn her giant Balenciaga pearl earrings before, during a trip to Paris, she showcased a similar statement necklace and gobstopper ring. Neither of the new pieces has yet been identified.

During her trip to Paris, Kate also wore a new Cartier set from the design house's Trinity collection. The interlinked circles of 18-karat white, pink, and yellow gold on both the earrings and necklace are suspended from a single diamond, with a price tag of $2,023 and $1,953, respectively.

Kate has always been a huge fan of Kiki McDonough earrings, but in 2017, the duchess debuted three of her most impressive sets by the designer. For a charity gala at the National Portrait Gallery, Kate wore a pair of pink tourmaline and green amethyst drops worth $12,235.

The duchess had worn Kate Spade dresses before but got on board the tassel train with a $100 crimson pair for a charity performance of 42nd Street.

It was $10,311 pink morganite drops from Kiki McDonough for Pippa Middleton's wedding.

Kate has worn a few sets of impressive jewels over the years, but her arrival in Warsaw marked the debut of a simple but striking set of mystery rubies and diamonds, comprising earrings, pendant, and ring. Similarities have been drawn between the suite of jewels and the work of former crown jeweler G. Collins & Sons — who is responsible for Kate's favorite tanzonite and diamond set — but the designer has never been publicly confirmed.

During her trip to Poland in 2017, Kate was gifted a set of earrings and necklace made from local Baltic amber, which she wore on her trip to the city of Gdansk.

There was plenty of bling on display for Kate's arrival to Berlin, thanks to new jewels from Kiki McDonough. The duchess chose to accentuate her Prussian blue Catherine Walker coat with the $1,607 Eden blue topaz and diamond flower necklace and complementing $4,019 blue topaz and diamond earrings.

Also during her trip to Germany, Kate teamed a $269 pair of red crystal Simone Rocha earrings with an Alexander McQueen gown.

Kate has a few Oscar de la Renta pieces hanging in her wardrobe, and during her trip to Germany, she also showed off her new $172 Pearl Star Button earrings, made from gold-plated pewter and glass pearls.

Kate has worn an Asprey diamond pavé button pendant since before she was married, but the matching $4,760 earrings have only been worn recently. Like the pendant, they are set around a central amethyst, and Kate has worn them a couple of times, including for a game of hockey on her first day in Sweden.

Also in Sweden, Kate continued her liking for wearing the work of local designers while on tour when she chose a pair of squished $150 pearl baroque drops from In2Design.

Kate's wedding earrings were created by classic jeweler Robinson Pelham, and the duchess has worn earrings by the same designer on a few occasions since. She recently sported its $6,754 Aspen diamond loops during an evening reception in Stockholm.
