Zara Tindall, niece of King Charles III, is drawing attention for her involvement in a jewellery line featuring pink diamonds sourced from the Argyle mine in Western Australia, a site with a contentious environmental record. The exclusive collection, developed alongside designer John Calleija, includes several pieces incorporating the gems, with prices reaching up to £21,600 for a ring set with 27 pink diamonds. Tindall, known for her support of environmental causes, was seen wearing earrings from the same collection at a Buckingham Palace garden party in May 2023.

The Argyle mine, which ceased operations in 2020, was responsible for producing approximately 90 percent of the world’s pink diamonds during its active years. It is owned by Rio Tinto, which has been conducting cleanup efforts over an area covering roughly 5,000 acres in the Australian Outback. Indigenous groups, including Gelganyem, which represents the traditional Aboriginal owners of the land, say the mine has caused lasting environmental damage. A report published by Gelganyem in 2023 detailed contamination of soil, groundwater, and surface water by PFAs—synthetic chemicals commonly referred to as "forever chemicals" due to their persistence in the environment. The report also highlighted severe erosion, the need for chemical testing of local fish, and harm to indigenous burial sites.

PFAs, or per- and polyfluoroalkyl substances, are widely used in products such as firefighting foam but are difficult to break down and have raised health and ecological concerns globally. The contamination has led Gelganyem to warn that land-use activities will be permanently limited in the affected areas.

In response to inquiries, jewellery designer John Calleija affirmed a commitment to sourcing gems ethically, stating that the brand takes care in choosing materials. Rio Tinto acknowledged the environmental issues linked to the mine and emphasized its efforts to manage these impacts responsibly, expressing a goal of a closure process that is safe, stable, and respectful of cultural sensitivities.

Gelganyem clarified that its comments are not meant to single out individuals but rather to encourage transparency and accountability from brands, suppliers, and public figures involved with the mine’s products. The group called for assurances that commitments to environmental rehabilitation and land restoration are being fulfilled. Tindall and her representatives have not provided specific comments on the concerns raised.
