Alrosa is betting on AI to uncover diamond deposits
Russia’s diamond giant Alrosa is betting on artificial intelligence to uncover deposits that have long eluded geologists.
The company revealed last week that it has created a digital system designed to pinpoint exploration zones with far greater precision, potentially reducing both the cost and the time traditionally required for diamond prospecting.
Explaining the rationale behind the initiative, Alrosa noted that most of the planet’s major kimberlite pipes—the richest sources of diamonds—were discovered decades ago. Since then, fresh finds have become increasingly rare.
The new platform draws on more than half a century of geological records, processing the data through neural network models to highlight areas still holding promise. Executives say the approach could mark a breakthrough in locating mineral resources.
Alrosa’s move comes amid mounting financial strain. Western sanctions, particularly from the G7, have curtailed the company’s sales channels, forcing temporary mine closures, a reduction in output, and even the transfer of unsold inventory to state reserves. Against this backdrop, the AI initiative signals both an urgent need for innovation and a long-term play to secure future resources.

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.
