British diver Yasmin Harper says her Olympic bronze medal is showing signs of “tarnishing” after American skateboarder Nyjah Huston criticised the quality of his medal.

Huston, who finished third in the men’s street skateboarding on 29 July, posted a video of his medal appearing to look discoloured and chipped.

Harper won Team GB’s first medal of Paris 2024, claiming bronze with partner Scarlett Mew Jensen in the women’s 3m synchronised springboard diving.

“There’s been some small bits of tarnishing,” said Harper after finishing fifth in the 3m springboard final on Friday.

“I think it’s water or anything that gets under metal, it’s making it go a little bit discoloured, but I’m not sure.”

However, Harper, 24, said she was not bothered by the situation “because it’s still a medal”.

Paris 2024 organisers said any damaged medals will be replaced.

In a series of Instagram stories, Huston said: “These Olympic medals look great when they’re brand new.

“But after letting it sit on my skin with some sweat for a little bit and then letting my friends wear it over the weekend, they’re apparently not as high quality as you would think.”
