Royal Oak Jewellery, the Okavango Blue and a Boucheron Archive: Five Jewellery Stories This Week
From a watchmaking icon finding a new life in jewellery to a remarkable collection of Boucheron treasures heading to auction in Paris, there’s been plenty to pique my curiosity this week. For my latest round-up, I’ve selected five of the week’s biggest jewellery stories, including a 20-carat blue diamond with a remarkable backstory, Tiffany’s case of the blues and some ingenious jewellery with secrets to reveal.

Audemars Piguet: When the Royal Oak Bracelet Becomes the Jewel
Audemars Piguet has taken one of the most recognisable bracelets in watchmaking history and turned it into a jewellery collection. Designed by Gérald Genta in 1972, the Royal Oak challenged watchmaking conventions with its octagonal bezel, exposed screws and integrated steel bracelet, whose tapering links, satin-brushed surfaces and polished chamfers were finished with an attention to detail more commonly associated with precious metals. The new Royal Oak Joaillerie collection dispenses with the watch entirely, transforming its iconic bracelet links into cuffs, necklaces and earrings.
The debut includes three lines. Dream of Joux introduces colour through one-of-a-kind cuffs in white, yellow and pink gold, as well as a tie necklace and earrings with pear-shaped diamonds and blue sapphire-set titanium links. Risoud Eclipse is darker, pairing black PVD titanium with diamonds and sugarloaf emeralds. The third line features Audemars Piguet’s signature “frosted gold” finish, the Florentine-inspired surface treatment it developed with Carolina Bucci in 2016. As CEO Ilaria Resta explains, the collection is part of a wider ambition to “revisit our codes” and explore jewellery alongside the house’s watchmaking activity.
Messika: Botswana on the Runway
Messika’s annual High Jewellery catwalk show has become a fixture of Paris Fashion Week. At the beginning of October, the house took over Galerie Courbe at the Grand Palais to showcase Terres de Contrastes, its latest High Jewellery collection. Continuing the Southern African journey begun in Namibia last year with Terres d’Instinct, for Terres de Contrastes Valérie Messika turned her attention to Botswana and three very different landscapes: the waterways of the Okavango Delta, the red and ochre expanse of the Kalahari desert and the pale mineral surface of the Makgadikgadi salt pans.
In the Okavango pieces, cascading diamonds evoke flowing water, while Féroce takes its angular forms from crocodile teeth. Règne uses onyx against gold to suggest feline markings, while Python Rubellite wraps the body in diamond scales interrupted by a deep rubellite. Colour is much more present than in Messika’s earlier diamond-led work, moving through blue, green, red, pink and white, according to the landscape that inspired it.
The show closed with Terres de Contrastes’ most important stone. The Okavango Blue began life as a 41.11-carat rough diamond. Today, it is a 20.46-carat oval VVS1 Fancy Deep Blue oval diamond, with the distinction of being the largest blue diamond discovered in Botswana and the eighth largest blue diamond in the world. Irina Shayk wore it for the final look of the show.
Sotheby’s Paris: Another Side of Boucheron
Boucheron is more often associated with exceptional diamonds, High Jewellery and its historic home on Place Vendôme, where it became the first major jewellery house to establish itself in 1893. This week, Sotheby’s Paris auctioned a collection of Extraordinary Objects by Boucheron in its Fine Jewelry sale, bringing together more than 40 archival creations from a single European family, spanning the late 19th century to the early 21st.
Among them was an 1880s gold photo frame, a 1920s lapis lazuli cigarette case set with sapphires and rose-cut diamonds and an Art Deco jade, enamel and lapis seal. These were objects made for everyday use, but Boucheron treated them with the same attention to materials and detail as its jewels, turning something as practical as a cigarette case or photo frame into an object worthy of collecting.
Tiffany HardWear: Turquoise, Pearls and Bunny Mellon
Launched in 2017, Tiffany & Co.’s HardWear collection was inspired by a gauge-link bracelet from the House’s archives. Since then, it has become one of the House’s most recognisable contemporary designs, but until now, made exclusively in gold and diamonds. For 2026, Chief Artistic Officer Nathalie Verdeille introduces turquoise and Japanese Akoya pearls, taking inspiration from a lapis lazuli and pearl necklace in the Tiffany archives once worn by American socialite and philanthropist Rachel Lambert “Bunny” Mellon.
The nine new designs include a hero necklace in which vivid turquoise beads and lustrous Akoya pearls alternate along the signature gold links, each held in place by a small pyramid-shaped gold setting. The 34-inch design has two integrated clasps and can be worn long, doubled or separated into a shorter necklace and bracelet. The turquoise is sourced from the United States and Mexico and colour-matched across the pieces, while the Akoya pearls come from Japan.
Simone Jewels: A Celestial Collection with Something Hidden
Singapore jeweller Simone Ng is marking 20 years of Simone Jewels with a five-part series revisiting ideas from the house’s past. Hidden Gems: Celestial Atlas is the fourth chapter, drawing inspiration from the stars, moons, suns, clouds and compass roses, and on the long history of travellers using the night sky to navigate.
The jewels have a few tricks up their sleeves. A Brazilian Paraíba tourmaline ring flips over to reveal a different design on its reverse, while sapphire and diamond earrings swivel to expose intricate guilloché patterns. Elsewhere, movable elements conceal gemstones that only become visible when the jewellery is opened or turned. It is a playful approach to High Jewellery, with plenty of surprises hidden in the details.
