Custom diamond necklace maps every Formula 1 track in Melbourne

Hannah St John arrived at Glamour on the Grid with a necklace that turned Formula 1 fandom into a piece of fine jewelry: a custom diamond design that traced the outlines of Grand Prix circuits and brought Melbourne’s pre-race spectacle into sharp, glittering focus. Worn ahead of the 2026 Australian Grand Prix, the piece landed like a status object and a fan tribute at once, exactly the kind of ultra-specific commission luxury clients are now chasing.

The necklace, named La Velocità, was created by Adelaide-based jeweler Martin Rogers. Coverage places its value between about $350,000 and $500,000, a price point that puts it well beyond novelty jewelry and squarely into high jewelry territory. It is said to contain nearly 1,800 diamonds totaling about 25 carats, with 250 to 300 hours of handcrafting behind the finished piece. Those numbers matter: this was not a logo pendant or a quick brand crossover, but a labor-intensive object built to translate a racing obsession into precious materials.

St John, identified in additional coverage as the partner of Racing Bulls driver Liam Lawson, wore the necklace in a setting made for attention, just as Formula 1 was preparing to open its 2026 season at Albert Park Grand Prix Circuit. Formula 1 lists the Australian Grand Prix for March 6-8, 2026, with the race itself on March 8, and also lists Lawson on the 2026 Racing Bulls grid. That context helped give the jewelry its charge. In the paddock, where fashion and status are already part of the language, a necklace that maps the sport’s circuits feels less like an accessory than a declaration.

For jewelers courting bespoke commissions, the lesson is clear. Clients are no longer satisfied with initials, birthstones, or broad symbols of prestige. They want pieces that encode identity with unusual precision, whether that means a favorite track, a private milestone, or a fandom that can be recognized only by those who know the reference. La Velocità shows how custom diamond jewelry is becoming spectacle in its own right: technically demanding, narratively rich, and designed to travel far beyond the person wearing it.
