Petra is to offer a 32.32-carat pink diamond at its first tender of goods from the Williamson mine, in Tanzania following a Covid-enforced closure.
The stone is among 26,000 carats that will be offered in Antwerp from 19 to 26 November.
The London-based miner classified Williamson as “an asset held for sale for financial reporting purposes” after a a debt-for-equity restructuring.
The open-pit mine was mothballed in April 2020 to “preserve its liquidity, at a time when diamond pricing was impacted by the COVID-19 pandemic”. Operations resumed in Q1 FY 2022.
