Cartier Sapphire and Diamond Ring.Estimate: HK$1,300,000 - 1,900,000. The Hong Kong Jewels Auction.
Under camera flashes on world stages, idols stand radiant and unafraid, transforming every step, glance, and gesture into a moment charged with cultural electricity.
Today, maisons enlist K-pop stars as global ambassadors, leveraging their presence to ignite new audiences and stir desire across continents. Signed creations, already coveted for their extraordinary design and historical weight, are reborn as emblems of confidence, cultural pride, and artistic identity.
Under the icons’ influence, high jewellery is admired and amplified: layered with leather, styled in gender-fluid ways, or worn with unapologetic flair.
Cartier
Few symbols carry the same magnetic force as Cartier’s Panthère, a creature of elegance and power reborn for a new generation through the radiant presence of BLACKPINK’s Jisoo and BTS’ V. Their ambassadorships capture the maison’s duality: heritage steeped in Art Deco codes, yet unafraid to pulse with contemporary charisma. As faces of Cartier’s Panthère, BLACKPINK’s Jisoo and BTS’s V bring radiant presence to a heritage reimagined with unapologetic modernity.
At Phillips, that energy finds exquisite form in two signed jewels. The Diamond, Emerald and Onyx ‘Panthère de Cartier’ pendant necklace channels the feline’s untamed spirit through its pear-shaped emerald eyes.
Cartier, Diamond, Emerald and Onyx Pendent Necklace, 'Panthère de Cartier'. Estimate: HK$80,000–140,000. The Hong Kong Jewels Auction.
Alongside it, an Art Deco diamond bracelet watch distills Cartier’s mastery of form into a piece that is both jewel and timekeeper, a design as timeless as it is daring. Both are signed Cartier, and they echo the fearless style of the idols who wear them, where brilliance prowls, radiant and unafraid.
Cartier, Art Deco Diamond Bracelet Watch, ca. 1929. Estimate: HK$1,200,000–2,200,000. The Hong Kong Jewels Auction.
Harry Winston
Harry Winston, once crowned the “King of Diamonds,” finds fresh resonance in the luminous presence of Park Hyung-Sik and Seungmin of Stray Kids. Park brought Winston’s timeless aura to life in his ELLE Japan cover story, while Seungmin channels a modern energy that makes diamonds feel as immediate as the beat of a song.
That dialogue between heritage and youth is echoed in two Winston creations at Phillips this season: a magnificent diamond rivière necklace and a pair of diamond ear clips, both signed Winston for Harry Winston, with maker’s mark for Jacques Timey. Together, they embody Winston’s eternal promise, elegance that captivates, yet pulses with the vitality of now.
Harry Winston, Diamond Necklace. Estimate: HK$380,000–500,000. The Hong Kong Jewels Auction.
Harry Winston, Pair of Diamond Ear Clips. Estimate: HK$580,000–680,000. The Hong Kong Jewels Auction.
Tiffany & Co.
Tiffany & Co. shines with modern rebellion through BLACKPINK’s Rosé, who has made Schlumberger’s whimsical designs and Tiffany Lock’s clean geometry feel like extensions of her own magnetic presence.
BLACKPINK's Rosé has been a global brand ambassador for Tiffany & Co. since 2021. Since then, she has been the face of several major campaigns, including the global launch of the Tiffany Lock collection in 2023. At the 2025 Met Gala, she wore a Tiffany High Jewellery necklace and ring featuring large sapphires and diamonds.
Schlumberger for Tiffany & Co., Diamond Bracelet, 'Hands'. Estimate: HK$200,000–300,000. The Hong Kong Jewels Auction.
The Tiffany-signed jewels at auction — including a Schlumberger “Hands” diamond bracelet, with its bevelled openwork band and brilliant-cut diamonds mounted in yellow gold and platinum, signed Tiffany & Co. Schlumberger STD — carry that same effortless blend of heritage and edge. These are pieces that transcend eras while speaking directly to the moment.
Piaget
Piaget’s bold retro glamour, encapsulated by Jun Ji-hyun, translates fresh rhythm into legacy. In April 2025, Piaget named South Korean actress Jun Ji-hyun its new global ambassador, fronting the bold Sixtie collection.
The brand’s legacy of audacious creativity is reborn in two standout signed jewels at this season’s auction. The carved agate and diamond “Rose” ring-pendant in white gold, signed Piaget, transforms a floral motif into wearable poetry, fusing discreet elegance with bold versatility. Its companion, the “Limelight Mediterranean Garden” cultured pearl and diamond necklace, drapes the neck in strands of pink pearls gathered by a pavé-set rose, and floats a collet-set brilliant-cut diamond — all in blush-pink gold, signed Piaget. It exudes the romance of vintage cinema romance with a contemporary edge.
Piaget, Agate and Diamond Ring/Pendant, 'Rose'. Estimate: HK$40,000–65,000. The Hong Kong Jewels Auction.
Piaget, Cultured Pearl and Diamond Necklace, 'Limelight Mediterranean Garden'. Estimate: HK$240,000–400,000. The Hong Kong Jewels Auction.
Bulgari
Bulgari has long embraced audacity, a quality mirrored in the youthful radiance of IVE’s Jang Wonyoung and the global magnetism of BLACKPINK’s Lisa. Wonyoung’s campaign for the Divas’ Dream collection channels her bright, unyielding energy, while Lisa’s long-standing role has brought serpents and bold forms into the rhythm of K-pop stages.
BLACKPINK’s Lisa, global ambassador since 2020, brings bold modernity to Bulgari, most memorably through Serpenti, B.Zero1, and her own limited-edition designs.
IVE’s Jang Wonyoung embodies Bulgari’s Divas’ Dream collection, her radiant energy and drive perfectly aligned with the maison’s DNA.
At Phillips, that spirit finds form in two masterworks: a Bulgari tanzanite and diamond ring, and diamond bracelet watch signed Bulgari. Each coils with the maison’s unmistakable daring — timeless in craftsmanship, yet alive with the pulse of icons who wear them as declarations of individuality.
Bulgari, Tanzanite and Diamond Ring. Estimate: HK$120,000–200,000. The Hong Kong Jewels Auction.
Bulgari, Diamond Bracelet.Estimate: HK$700,000–900,000. The Hong Kong Jewels Auction.
Graff
Graff, the British jeweller synonymous with rarefied brilliance, discovers new light through Sana of TWICE, whose presence brings fresh vitality to the maison’s Butterfly and Wild Flower collections. Through her, Graff’s creations transcend stillness, becoming emblems of movement and grace.
This season, Phillips presents jewels that capture that same ethereal energy: a Graff diamond Butterfly ring, delicate yet dazzling; and a Graff pair of ruby and diamond rings each pavé-set with circular-cut rubies. Both pieces, signed Graff, embody the maison’s craftsmanship while echoing the luminous aura Sana projects, where jewellery is not merely worn, but lived in.
Graff Diamond Ring.Estimate: HK$620,000–900,000. The Hong Kong Jewels Auction.
Graff Pair of Ruby and Diamond Earrings, 'Bombé'. Estimate: HK$190,000–260,000. The Hong Kong Jewels Auction.
