Petra rises on sparkling results

Petra Diamonds’ share price climbed over three per cent yesterday, after the diamond miner reported a 55 per cent increase in third-quarter revenue to $163.9m (£97m). The FTSE 250 company said it is “firmly on track” to meet its full-year production target of around three million carats. Revenue will be weighted towards the second half of the year due to the usual seasonal timing of Petra’s diamond sales, with two more tenders scheduled this year.
