Tiffany & Co. on your mind this Christmas? These are our editor in chief's favourite pieces

Nothing sparks festive joy quite like the robin-egg blue of a Tiffany & Co. box nestled under a Christmas tree. Whether you're perfecting your own gift list, searching for the perfect piece for a loved one, or simple want to invest in a glittering new accoutrement to wear throughout the holidays – make the iconic jeweller your mecca.

Here, we step into Tiffany & Co.'s Stockholm flagship with Vogue Scandinavia's editor in chief Martina Bonnier, who is well-versed in the intricacies of the jeweller's archives and current collections, to take note of her own stand-out pieces. From the HardWear pieces she first spotted on Lady Gaga, to the influential work of Jean Schlumberger for the house in the '50s, see all of Bonnier's favourite designs below.

Inspired by the attitude and energy of New York City, the HardWear collection "brings an edgier dynamic", in Bonnier's words, to Tiffany & Co.'s repertoire. "I remember the first time I saw the HardWear pieces," the editor in chief recalls. "Lady Gaga was wearing the necklace and it just looked so cool." HardWear has now grown into an extensive collection, eyewear inclusive, but Bonnier's eyes are on the necklaces in particular. "The link construction is so striking," she says of the magnified polished 18k gold piece. She styles it with the more delicate Double Link Pendant necklace, with one link coated in eye-catching pavé diamonds. "It's both industrial and elegant," she remarks.

Marked with a sleek T motif, Tiffany & Co.'s Tiffany T designs are a "masterclass in streamlined, graphic design," according to Bonnier. Her top pick is the T1 ring in 18k rose gold, with its statement shape and beveled details. "It's such a statement to wear, and has the versatility to be easily be mixed and matched with other rings. It's modern and you can wear it every day" An heirloom that speaks directly to the House's codes.

"The Lock collection is clean and classic", says Bonnier, "but also very notable for its genderless approach – which I love." Stemming from one original key bangle style (inspired by a padlock motif from the archive) the Lock collection now boasts several variations, with Bonnier honing in on the 18k gold earrings this season which are accented with diamonds totalling .19 carats. "I love the way they sit, and the innovative clasp mechanism," she says. "And while the full Lock collection is stunning, I can't go past the pieces that have the diamond pavé embellishment – which lights up the face."

"Jean Schlumberger’s work for Tiffany & Co. is simply iconic," says Bonnier. Sophisticated and deeply imaginative, this is a range that truly captures the artistry of the house – and its expert craftsmanship. This season, Bonnier singles out the Eighteen Stone Ring as a top pick: an 18k gold and platinum piece hosting .72 carats of round brilliant diamonds and gleaming tsavorites totalling .67 carats. "Pieces like this add a pop of gorgeous colour to your look – and the details are just mesmerising."

“While Jean Schlumberger was influential in the '50s, Elsa Peretti brought her legacy to the house around the '70s," Bonnier notes. The appeal of her distinctive, organic aesthetic endures today – remaining as modern as ever. Within the Stockholm flagship, it's the designer's 18k Small Bone Cuff that Bonnier turns to. "It's almost surrealist in its shape, with its fluid movement. I love how the asymmetrical contours of the piece counter the rest of my collection. It's a true statement that any jewellery-lover will instantly recognise."
