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.

PM Modi to visit Namibia; seeks to deepen economic ties in the diamond sector

Indian Prime Minister Narendra Modi is slated to visit Namibia on July 9, part of a five-nation tour that also includes Ghana, Argentina, Brazil, and Trinidad and Tobago. The trip marks Modi’s first official visit to the Southern African nation and underscores New Delhi’s ambition to deepen economic ties in the diamond sector.
While Indian firms such as Ankit Gems and KGK already run cutting and polishing units in Namibia’s capital, Windhoek, rough stones currently reach India indirectly via other global trading hubs. Modi’s visit is expected to pave the way for more direct diamond shipments, streamlining trade flows between the two countries.
Namibia ranks as the world’s fifth-largest diamond producer by value and volume, according to Kimberley Process data, and is especially known for its rich marine diamond reserves, estimated at over 80 million carats.
The agenda extends beyond gemstones. Modi is also set to discuss cooperation on critical minerals and uranium—resources vital to India’s clean energy ambitions and energy security. During the visit, he is scheduled to address the Namibian Parliament, signaling the strategic importance New Delhi places on closer engagement with Africa’s resource-rich economies.

Diamond Market Rebounds in 2025; India Emerges as Global Growth Engine

The global diamond industry is showing signs of revival in 2025, following two years of sluggish demand. According to Susan Jacques, President and CEO of the Gemological Institute of America (GIA), the gem and jewellery sector faced significant headwinds after a brief boom in 2021, which was fueled by pandemic-era shifts in consumer spending and travel behavior.
While 2022 saw strong pricing and demand, a downturn took hold through 2023 and 2024. Now, a renewed sense of optimism is emerging. “The recovery was expected, and we’re beginning to see positive momentum return,” Jacques noted.
A key driver of this rebound is India, whose cultural affinity for diamonds continues to underpin strong consumer interest. Over the past two decades, India’s share of global diamond demand has surged from just 2% to nearly 11%, positioning it as the world’s second-largest market for natural diamonds—trailing only the United States, which remains dominant with around 55% of total sales.
Pritesh Patel, Senior Vice President and Chief Operating Officer at GIA, remarked that the US market has remained stable in early 2025, and industry stakeholders are optimistic about sustained demand. In India, he observed a notable shift: interest in diamonds is expanding well beyond major metropolitan areas.

“Tier-2 and tier-3 cities are now driving growth, alongside established hubs,” Patel said. He added that demand is strong across India’s southern, northern, and western regions, signaling a broad-based recovery in diamond jewellery purchases.
The global industry is cautiously optimistic as it navigates 2025, buoyed by emerging markets and a renewed appetite for luxury adornments.
