GJEPC Hosts De Beers’ Sean Lin for strategic discussions on reviving natural diamond demand in China
De Beers and GJEPC explore deeper collaboration to boost natural diamond demand in China amid improving consumer sentiment and a clear price divide with lab-grown diamonds.
Sean Lin, VP Sales, De Beers Group, visited the GJEPC head office in Mumbai on 27 November, where he was received by Kirit Bhansali, Chairman, GJEPC; Shaunak Parikh, Vice Chairman, GJEPC; Anoop Mehta, Convener – Diamond Panel, GJEPC; Ashish Borda, Convener – PMBD, GJEPC; and Ajesh Mehta, former Convener – Diamond Panel, GJEPC. The meeting touched on strengthening collaboration to promote natural diamond jewellery in China, including ongoing work with Chow Tai Fook.
Lin noted that consumer interest in natural diamonds is gradually improving, supported by signs of market recovery. He also shared that lab-grown diamonds in China largely remain in the low price, accessory-style segment, typically under USD 150 and sold through mass retail formats. This trend is helping preserve the value perception of natural diamonds among Chinese consumers.
Both sides discussed ways to deepen cooperation and support natural diamond jewellery category growth through targeted promotional initiatives and consumer education.

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.
