Zara Tindall promotes £21,600 pink diamond rings from an Australian mine at the centre of a 'forever chemicals' row

Ellie Goulding was 'mortified' after wearing the same Argyle pink diamonds, making Zara Tindall the second high-profile figure caught up in the controversy over stones from the Western Australian mine. Rio Tinto has acknowledged that PFAS-containing firefighting foam was 'historically widely used' at the Argyle site and is now undertaking rehabilitation across 5,000 acres of contaminated land.
Designer John Calleija has defended sourcing, saying his firm has been 'fastidious' about materials for more than 40 years.
The indigenous traditional owners of the Argyle land say the mining process involved 'forever chemicals' that are virtually impossible to break down.
Zara and husband Mike Tindall are supporters of Blue Marine Foundation, an ocean conservation charity — lending a conservation irony to the controversy.
