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.

Motorsport Meets High Jewellery: Hannah St John Turns Heads with ‘La Velocita’ Diamond Necklace at F1 Event
A 25-carat, 1,800-diamond Masterpiece Inspired by Formula 1 circuits Takes Centre Stage at the Glamour on the Grid ahead of the Australian Grand Prix
At the glamorous lead-up to the Australian Grand Prix, Hannah St John, partner of Liam Lawson, made a striking statement at the Glamour on the Grid event with a one-of-a-kind diamond necklace that seamlessly blended motorsport and haute jewellery.
Titled “La Velocit” (The Speed), the necklace was crafted by Australian atelier Martin Rogers Jewellery. The extraordinary piece features approximately 1,800 diamonds totalling 25 carats, intricately arranged to trace the outlines of iconic Formula 1 circuits from the global racing calendar.



A true testament to craftsmanship, the necklace required an estimated 250–300 hours of meticulous handwork, including weeks dedicated solely to precision diamond setting. Valued at around AUD $500,000 (approximately $350,000 USD), the piece stands as a bold fusion of speed, design, and luxury artistry.
Blurring the lines between engineering inspiration and fine jewellery, “La Velocità” captured attention across the paddock, proving that Formula 1’s influence extends far beyond the track.
