This week, Russian diamond mining giant Alrosa announced that the first initial tests by local scientists and company experts on how kimberlite waste ore – what’s left of the super hard rock in which rough diamonds are found once the diamonds are recovered – can be used to absorb carbon dioxide, showed promising results, potentially even compensating the 997k tonnes of CO2 emissions generated by the entire company in a full year. The company aims to further reduce its footprint by shifting from fuel-powered to renewable energy throughout its operations.

The Economic Times India reports that, with the all but last sale of Rio Tinto's Argyle Pink diamonds, the precious fancy colored stones have become increasingly popular among India's high net worth individuals. In the past decade, the rare pinks' value has grown significantly, year after year, and prices are estimated to go up even further as the world's primary source, the Argyle mine in Australia, is set to close soon. That scarcity is also making other high quality diamonds an interesting investment, as no major mines have been discovered in recent years.
In a virtual preview, Rio Tinto has showcased its 2020 Argyle Pink Diamonds Tender, entitled One Lifetime, One Encounter, one of the last of a series of annual tenders held since the exceptionally rare pink, violet and blue diamonds were first discovered in the Western Australian Argyle mine in 1979.

Despite the global pandemic and the challenges it poses on the diamond industry at large, Rio Tinto, owner of the Argyle mine in Australia and partial (60%) owner of the Diavik mine in Canada, has continued to produce and market its rough diamonds.

Via its Antwerp office, the only diamond hub that remained open for business throughout the crisis, the miner also recently held a Rio Tinto Specials Tender.
A Canadian judge has ordered the Rio Tinto subsidiary, in the joint venture managing the Diavik mine, to release Dominion's share of production that Rio Tinto has been holding as collateral for overdue payments.

Diamonds is a business we like a lot. It’s a very high-margin business in line with our strategy of value over volume. It makes a lot of sense. We want to stay in the diamonds business, so we have committed 20% of our exploration budget to diamonds. We are also exploring for mergers and acquisitions.
- Arnaud Soirat, Rio’s chief executive for copper and diamonds, speaking to Bloomberg
