Zara Tindall's jewellery range features controversial Argyle mine diamonds

Summarised from 2 outlets · Updated 31 Oct, 17:13 · Archive

Zara Tindall is selling jewellery featuring pink diamonds from Australia's Argyle mine, which environmental groups say caused pollution through 'forever chemicals'.

Zara Tindall, King Charles' niece, has been selling jewellery featuring pink diamonds from Australia's Argyle mine through a range with designer Calleija. The collection includes at least four designs, among them a platinum Suprema Saddle ring set with 27 Argyle pink diamonds priced at £21,600, and matching pendant and earring sets. The ring is described as reflecting Tindall's love of equestrian eventing.

Traditional owners of the land say the mining process involved 'forever chemicals' that destroyed the environment. Rio Tinto, the mining company, has begun a clean-up operation across 5,000 acres. Calleija's website notes that as the mine has come to the end of its life, owning an Argyle Pink Diamond is now rarer than ever.

Tindall attended a Buckingham Palace garden party in May 2025 wearing Sidra earrings from the collection featuring Argyle pink diamonds. She and her husband Mike support ocean conservation charity Blue Marine Foundation. The controversy comes after singer Ellie Goulding, a WWF ambassador, said she was 'mortified' to have worn a half-million-pound necklace and earring set containing the same stones.
