Tiffany & Co. Unveils Empire Diamond Necklace Featuring 80-Carat Flawless Gem, Its Most Valuable Jewel for Sale
Featuring an 80-carat, D-colour, internally flawless diamond, the $20 million necklace blends Art Deco heritage with modern craftsmanship—and is the first of its kind from Tiffany to be offered for sale.
Tiffany & Co. has introduced the Empire Diamond Necklace, the most valuable piece ever offered for sale by the iconic jewellery house. The show-stopping centrepiece is an 80-carat, D-colour, internally flawless oval diamond, set in a platinum necklace inspired by a historic Art Deco design.
Valued at over $20 million, the necklace reimagines a piece originally created for the 1939 World’s Fair, which featured a 200-carat aquamarine. The new version replaces it with one of the rarest white diamonds in the world—sourced in Botswana, cut in Israel, and finished at Tiffany’s New York City workshop. Named after the Empire State, the diamond is celebrated for its chemical purity and perfect clarity.
The necklace is adorned with 578 diamonds—including 353 round brilliants and 224 custom-cut baguettes—arranged in a refined Art Deco silhouette. Notably, the centre diamond is removable and can be worn as a ring, enhancing its versatility.
The Empire Diamond Necklace debuted at Tiffany’s Blue Book event in Dubai and quickly garnered global attention. Beyoncé was the first to wear it publicly, including at her 2022 Oscars afterparty and in a British Vogue feature.
While Tiffany’s famous 128.54-carat Tiffany Diamond remains its most iconic (and not for sale), the Empire Diamond Necklace is the first of such calibre to be made available for purchase—solidifying the brand’s position at the pinnacle of luxury and high jewellery design.

Diamond Slump forces Debswana to diversify into copper, platinum and solar
Diamond-centric mining models is giving way to broader resource portfolios
Debswana Diamond Company, the 50–50 joint venture between the Botswana government and De Beers, is moving to diversify into copper, platinum and renewable energy as the prolonged downturn in natural diamond demand pressures earnings and forces the industry to rethink its growth strategy.
The company’s board has approved plans to invest in a portfolio of non-diamond projects after revenue fell 46% in 2024, the latest available financial year, highlighting the scale of the downturn in the global diamond market.
The move signals a strategic shift toward commodities with stronger long-term demand fundamentals, particularly copper, which is central to global electrification and energy-transition infrastructure.
Debswana’s diversification reflects a broader industry pivot as diamond producers confront weak consumer demand, rising competition from lab-grown stones and elevated inventories across the supply chain.
The shift is also visible among smaller exploration companies. Botswana Diamonds recently rebranded as Botswana Minerals, signalling its own strategic focus on copper exploration rather than diamonds.
Together, these moves underscore a growing consensus across the sector: the era of diamond-centric mining models is giving way to broader resource portfolios anchored in energy-transition metals.
