Alrosa considering to establish diamond polishing facility in India
Alrosa is reportedly considering a move to establish its own diamond polishing facility in India located in Surat or Jaipur, at an estimated cost of $50m, and it would represent Alrosa’s first overseas expansion, according to the Economic Times.
Alrosa, the world’s largest diamond producer by volume, currently focuses on rough diamond extraction and sales, with limited domestic polishing in Siberia and Moscow targeting smaller stones for local markets. A $50 million plant in Surat or Jaipur would mark its first overseas manufacturing venture, tapping into India’s dominance in 90% of global diamond cutting and polishing. This downstream expansion aims to boost efficiency, scale, and direct access to skilled labor and international buyers, reducing reliance on intermediaries.
India’s booming jewelry market, fueled by a rising middle class and double-digit growth, positions it as the second-largest diamond consumer after the US. The move could help Alrosa navigate sanctions, US tariffs, and “Russian origin” scrutiny by polishing abroad, easing entry into key markets. Beyond polishing, plans include co-branded luxury jewelry lines and blockchain traceability, fostering deeper ties with Indian manufacturers.

Rio Tinto’s Diamond Division Posts $79 Million EBITDA Loss in 2025
Higher output from Canada’s Diavik Diamond Mine offsets revenue decline, but end-of-life pressures continue to weigh on performance.
Rio Tinto reported a challenging year for its diamond business in 2025, posting an underlying EBITDA loss of $79 million despite improved revenues. While the loss narrowed compared to the $115 million deficit recorded in 2024, the division remained under pressure amid a global diamond market slowdown and the nearing closure of its last active mine.
Annual revenue rose 19% to $332 million, supported by stronger production at the Diavik mine in Canada, Rio Tinto’s only remaining diamond operation. Output climbed 61% to 4.4 million carats, driven by the ramp-up of mining activities in the underground section of the A21 deposit, which began scaling up in late 2024.
However, the A21 underground ore body is expected to be depleted by the end of the first quarter of 2026, marking the end of Diavik’s operational life. The company plans to spend approximately $1 billion this year on closure activities related to Diavik, as well as rehabilitation work at the former Argyle Diamond Mine, which ceased production in 2020, and other non-diamond projects.
