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.

GIA, Gübelin Gem Lab Confirm Rare Tourmaline Discovery In Ethiopia
The Testing Revealed hat While The Stones Exhibit The Signature Electric Blues, Bluish-Greens, Violets, and Purples Typical Of Copper-Bearing Elbaite, Their Trace-Element Profile Is Distinct From South American and West African Counterparts.
Two of the world’s foremost gemological authorities have verified the discovery of a significant new source of rare, copper-bearing tourmaline in Ethiopia, adding a major new supplier to one of the luxury jewelry sector’s most valuable gemstone markets.
Independent testing conducted by the Gemological Institute of America (GIA) and Switzerland-based Gübelin Gem Lab confirmed that newly circulating rough material originates from an Ethiopian deposit and qualifies as the coveted “Paraiba” variety. Historically, supply of the vivid, copper-infused gemstone has been restricted to limited deposits in Brazil, Nigeria, and Mozambique.
Reports of Ethiopian material first emerged across global trading networks in early 2026 as unrefined stones began appearing on international markets. Gübelin acquired and tested roughly 300 rough and cut specimens in May, while the GIA analyzed a parcel of more than 100 stones in July to establish origin baselines.
The testing revealed that while the stones exhibit the signature electric blues, bluish-greens, violets, and purples typical of copper-bearing elbaite, their trace-element profile is distinct from South American and West African counterparts.
Many specimens also display pronounced internal color zoning corresponding to subtle variations in chemical concentration during crystallization.
Both laboratories stated they will continue expanding their reference databases and analytical testing as commercial mining operations mature and additional Ethiopian rough enters the global supply chain.
