Diamond prices generally declined in September
Diamond prices generally declined in September, with notable sharp drops for round polished goods under 1 carat. The market was affected by US tariffs and the ongoing sale of De Beers, creating uncertainty.
- Key Declines:
- The RapNet Diamond Index (RAPI™) for 1-carat (round, D-H, IF-VS2) fell 0.9%.
- RAPI for 0.30- and 0.50-carat goods both dropped 6%.
- SI-clarity 1-carat rounds saw a larger decline of 2%.
- Strong Segments: Prices for larger sizes were mixed, but long fancy shapes, particularly in 2 carats and up, were “hot.” RAPI for 3 carats was flat.
- Trade & Tariffs: Demand at the Hong Kong show favored larger diamonds/fancies. US tariffs (especially the 50% rate on Indian goods) restricted overseas sales to the American market, despite steady business for independent US jewelers. The EU secured a zero-tariff deal, and Botswana is negotiating one.
- Production: Indian manufacturers cut polished production due to weak demand; August rough imports fell from July ($1.15 billion to $768.7 million).
- De Beers: The sale of Anglo American’s De Beers unit was in progress, with Botswana seeking a majority stake and Angola bidding for a minority holding.

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.
