Asap Rocky gifted Rihanna a $400K diamond watch as an anklet for the Las Vegas F1 Grand Prix

Rihanna wowed the crowds at the Formula 1 Las Vegas Grand Prix on Saturday by donning a daring black ensemble and a six-figure custom Jacob & Co. watch around her ankle. Her attire was particularly eye-catching.

The 35-year-old “Diamonds” vocalist displayed the 18-karat white gold piece, valued at $400,000, atop a pair of black Balenciaga pantaleggings that cost $4,550. The dark fabric accentuated the magnificent accessory.

Three strands of diamonds adorn the strap of her Jacob & Co. timepiece, which in total contains seventy carats of round, emerald-cut stones.

In addition to her mesmerizing anklet, Rihanna adorned herself in a number of diamond statement pieces by Messika, including a dazzling ear clip, three-strand necklace, and statement ring.

Rihanna, who did not appear on the starting platform with other celebrities, maintained a low profile at the event, according to a source who spoke to Page Six Style, despite the fact that her accessories were anything but understated.

Additionally, she attended the event donning a pair of dark sunglasses by Ambush, which she maintained on for the majority of the race while observing the proceedings in the Ferrari garage with other VIPs.

The event was attended by numerous celebrities, including Gordon Ramsay, Kylie Minogue, Heidi Klum, Paris Hilton, John Legend, and Rod Stewart, in addition to the “Umbrella” vocalist.

Unsurprisingly, her 35-year-old companion A$AP Rocky also participated, unveiling his Puma x F1 collection on Friday evening.

Not only has Rihanna displayed a $600,000 pear-shaped diamond ring as a foot adornment while out on the town in May, but she has also displayed significant jewelry during her Formula One moment.

Continue to shine, RiRi.
