Annie Doresca Named CEO of Diamond Council of America
Veteran Jewelry Executive and DEI Advocate to Succeed Terry Chandler, Will Lead DCA While Continuing Role at Jewelers of America
Annie Doresca, chief financial and operating officer of Jewelers of America (JA), has been appointed CEO of the Diamond Council of America (DCA), effective January 1. She will succeed longtime leader Terry Chandler and will continue in her current role at JA while also serving as executive vice president of the DCA until the transition is complete.
The DCA board selected Doresca for her proven leadership, business expertise, and dedication to advancing the organization’s mission. Her dual role aims to strengthen the collaboration between JA and DCA, which became affiliated organizations in recent years.
Doresca brings extensive experience to the position. Since joining JA in 2008, she has helped steer its financial strategy and operations. She is also the founding president of the Black in Jewelry Coalition (BIJC), a leader in promoting diversity, equity, and inclusion within the jewelry sector.
Beyond her executive roles, Doresca serves on multiple industry boards, including the Jewelers Vigilance Committee (JVC), Jewelers’ Security Alliance (JSA), Jewelers Board of Trade (JBT), and the Women’s Jewelry Association Foundation.

Outgoing CEO Terry Chandler expressed strong support for his successor. “Annie has already made significant contributions to the DCA’s growth,” he said. “Her leadership will undoubtedly elevate the organization and empower countless jewelry professionals through education and opportunity.”
With Doresca at the helm, the DCA is poised to strengthen its role as a vital educational resource in the jewelry industry.

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.
