Historic Mughal Emerald Jewels to Lead Christie’s Magnificent Jewels Auction in New York
Over 2,000 carats of rare Mughal-era emeralds and multi-gem treasures — including a 470-carat centerpiece — headline a landmark sale alongside prestigious pieces from Anne Bass and Lucille Coleman collections.
Christie’s will showcase an extraordinary array of Mughal jewels at its upcoming Magnificent Jewels auction in New York on June 17, led by a remarkable carved emerald necklace bearing over 1,150 carats of Colombian emeralds. The historic piece is inscribed with the name Ahmad Shah Durrani, founder of the Durrani Empire, and features a massive 470-carat central emerald. Dating back to 1612, this jewel is steeped in royal heritage and has been linked in historical records with other legendary gems such as the Timur Ruby and the Koh-i-Noor diamond. It carries a pre-sale estimate of up to $3 million.
Two additional Mughal masterpieces will also feature in the sale. One is a multi-gem necklace set with four Colombian emeralds totaling nearly 800 carats, expected to fetch up to $3 million. The other is a remarkable necklace strung with over 2,000 carats of spinel and natural pearls, with eight stones engraved with the names of influential rulers including Delhi Sultan Muhammad ibn Tughluq, Mughal emperors Babur, Jahangir, and Shah Jahan. That piece is estimated to sell for as much as $2 million.
These jewels will be presented alongside the personal collection of philanthropist Anne Hendricks Bass, which includes 26 pieces from esteemed design houses such as Van Cleef & Arpels, Bulgari, Cartier, and JAR. A standout from this collection is a pair of Van Cleef & Arpels diamond pendant earrings, estimated at up to $1.8 million, and a JAR sapphire, emerald, and diamond necklace, valued at up to $300,000.
Also featured in the auction is a group of nine Van Cleef & Arpels Mystery-Set jewels from the collection of philanthropist Lucille Coleman, described by Christie’s as a “significant” highlight of the sale.
With its blend of historical depth and iconic 20th-century design, the June auction promises to be one of the most compelling jewelry events of the year.

DDE, LDB Sign MoU
Dubai Diamond Exchange (DDE) and the London Diamond Bourse (LDB) have signed a Memorandum of Understanding (MoU) aimed at strengthening cooperation between the two diamond trading centres, expanding business opportunities for members, and promoting responsible growth across the global diamond and gemstone trade. The agreement was announced on 8 July 2026.
The MoU establishes a framework for collaboration in responsible trading, commercial development, knowledge sharing, and closer engagement between members of the two bourses. It also seeks to encourage dialogue on issues affecting the international diamond industry as trading centres adapt to an increasingly interconnected global marketplace.
The agreement was signed by Ahmed Bin Sulayem, Chairman of the Dubai Diamond Exchange, and Charlotte Rose, President of the London Diamond Bourse. It marks the first formal international partnership under Rose’s presidency, which began in June.
Ahmed Bin Sulayem, Chairman, Dubai Diamond Exchange, said:
“The Dubai Diamond Exchange was built on the belief that connecting markets creates opportunity. This partnership with the London Diamond Bourse reflects that philosophy, bringing together two major diamond trading centres to strengthen collaboration and expand opportunities for our respective members. The future of our industry will not be built by individual markets acting alone. By working more closely together, we can establish a stronger network of trusted trading centres, sharing expertise, upholding recognised standards, and reinforcing confidence and growth across the global diamond trade.”

Charlotte Rose, President, London Diamond Bourse, noted:

“There is no better partner for the London Diamond Bourse to begin this new chapter with than the Dubai Diamond Exchange. As a fellow member of the World Federation of Diamond Bourses, the DDE shares our commitment to trusted, well-governed trading, and this agreement opens up real opportunities for members on both sides. I’m looking forward to seeing where this partnership takes us.”
