Christie’s present The Golconda Blue:the largest fancy vivid blue diamond offered at auction
Christie’s is proud to present The Golconda Blue—the largest Fancy Vivid Blue Diamond ever to be offered at auction. Weighing an extraordinary 23.24 carats, this superb historic gemstone will headline Christie’s Magnificent Jewels sale, taking place live on 14 May 2025 at the Four Seasons Hotel des Bergues in Geneva, with an estimate of $35 – 50 million. The Golconda Blue, perfectly mounted in a ring by JAR, is a true masterpiece with its recently uncovered royal provenance, mesmerizing colour, and sensational size. It ranks among the rarest and most important diamonds ever discovered throughout history.
This exceptional pear-shaped Golconda diamond boasts a remarkable provenance rooted in Indian Royalty. Yeshwant Rao Holkar, the Maharaja of Indore and a member of the Holkar dynasty, was known—alongside his wife—for a lifestyle defined by elegance and cosmopolitan sophistication in the 1920s and ’30s. A Knight of the Order of the Indian Empire, the Maharaja spent much of his time abroad, cultivating a strong affinity for Western art, design, and jewellery.
In 1913, his father acquired the famed Indore Pear diamonds from Chaumet, marking the beginning of a long-standing relationship with the historic Parisian Maison. In 1923, during another visit to Chaumet, he commissioned a diamond bracelet set with his own 23-carat pear-shaped Golconda blue diamond.
Drawn to the firm’s avant-garde flare, Yeshwant Rao Holkar appointed Mauboussin as his official jeweler in 1933. Thereafter, Mauboussin reimagined much of the Maharaja’s collection and created the exceptional necklace including the Golconda Blue and the Indore Pears, worn by the Maharani of Indore memorialized in a portrait by Bernard Boutet de Monvel (illustrated on top of release).
Yeshwant Rao Holkar also collaborated with other iconic jewelers, including Harry Winston. In 1946, Mr. Winston purchased the Indore Pears from the Maharaja, and the following year, in January 1947, he acquired this 23-carat blue diamond. Winston later set it in a brooch alongside a matching 23-carat white diamond, which he sold to the Maharaja of Baroda. The brooch was subsequently reacquired by Mr. Winston and resold as a newly designed jewel to its current owner.
Now, over a century later, this legendary blue diamond comes to auction for the very first time, set as a striking contemporary ring by the celebrated Parisian designer JAR.
The legacy of Golconda diamonds begins with a reference found in a 4th-century Sanskrit manuscript. In 327 BC, Alexander the Great brought diamonds from India to Europe, sparking the West’s enduring fascination with these rare gems. By 1292 AD, Marco Polo famously chronicled the captivating beauty of Indian diamonds in his travel writings. Today, The Golconda Blue stands not only as a natural marvel but also as a storied jewel—its provenance bridging continents, dynasties, and centuries.

De Beers Presents “Voyage Through the Diamond Realm” at India Art Fair 2026 Featuring Lakshmi Madhavan
Immersive Installation Blends Natural-Coloured Diamonds with Lakshmi Madhavan’s Kasavu Art at India Art Fair 2026
De Beers unveiled “Voyage Through the Diamond Realm,” at India Art Fair 2026. The immersive installation invites audiences to explore the mythical origins of diamonds. Through visual storytelling, scenography and soundscapes, the installation reveals the living heritage of diamonds, their cosmic and earthly journeys across time.
Positioned at the intersection of art, nature and human expression, the experience acknowledges diamonds beyond adornment — recognizing them as treasured masterpieces shaped by billions of years of time, pressure, and transformation. The multi-sensory narrative, drew parallels between geological creation and artistic practice, revealing how nature, much like art, produces enduring expressions of beauty, rarity, and emotion.

Speaking on the installation and its India debut, Shweta Harit, Global Senior Vice President, De Beers Group, said, “Natural diamonds are among nature’s most extraordinary artworks, formed over billions of years, each one entirely unique. Presenting Voyage Through the Diamond Realm at India Art Fair feels fitting, diamonds are cultural artefacts, that inspire artistic dialogue which feels deeply relevant to India.
Our collaboration with artist Lakshmi Madhavan brings together two worlds of creation, one born deep within the earth, the other shaped by generations of human hands, while our association with India Art Fair reinforces our belief that art is a powerful lens through which material, heritage and meaning can be reimagined.”
Following its debut at Frieze Masters, London in 2025, the India edition underscored De Beers’ continued commitment to the country and deepened the narrative through a collaboration with contemporary artist Lakshmi Madhavan. Her installation featuring Kasavu, Kerala’s traditional gold-bordered handwoven textile, emerged as a compelling focal point.
Developed in collaboration with the Balaramapuram weaving community, the Kasavu installation served as a human counterpoint to the diamond. Together, diamonds and Kasavu revealed shared themes of time, continuity, craftsmanship and transformation.
Reflecting on the collaboration, Lakshmi Madhavan said, “I am truly excited to be part of this collaboration, which allowed me to work with a material that holds as much history, heritage, and cultural meaning as my core material — the Kasavu textile. Adornment emerged for me as one of the earliest human impulses, where materials gain meaning only in relation to the body.

Created in collaboration with the Balaramapuram Kasavu weaving community, the installation positions Kasavu as a human analogue to the diamond. Both materials carry histories of time and transformation and are activated through wear, touch and lived ritual.”
A unique highlight of the installation was the presentation of four exceptional natural-coloured diamonds — Pink, Orange, Light Blue and the rare Chameleon diamond, known for its remarkable ability to temporarily change colour to yellow when gently heated, before returning to its original hue. Displayed as individual expressions of geological artistry, the gems embodied the extraordinary diversity and rarity found in nature.
Adding to this showcase was a five-carat exceptional Forevermark diamond, accompanied by a ring design created by the Milan-based design team, offering interested collectors the opportunity to translate nature’s artwork into a contemporary piece of fine jewellery.
Presented in partnership with India Art Fair, the exhibition reinforced the role of collaborative platforms in expanding cultural dialogue and artistic awareness in India.
The opening reception drew a distinguished gathering from across film, art, design and culture. Among those in attendance were actor Khushi Kapoor, producer and fashion entrepreneur Rhea Kapoor, artist Ravi Vazirani, Yashwant Holkar, Lavina Baldota, designer Tahir Sultan, architect Khsuhnu Hoof among others.
Extending its engagement with India’s art ecosystem, De Beers also hosted an evening in collaboration with India Art Fair’s Young Collectors Programme.The event brought together emerging collectors, creative professionals and young cultural voices for an intimate experience of Voyage Through the Inner Realm, fostering dialogue around art, materiality and strengthening the foundations of India’s contemporary art landscape.
Through its presence at India Art Fair 2026, De Beers’ reaffirmed its commitment to cultural dialogue, craftsmanship and responsible luxury, positioning natural diamonds within a broader narrative where nature itself is the ultimate artist.
