  • De Beers decreased its rough diamond production in Q2 by 14% to 7.7 million carats and revised its full-year guidance downwards to ~31 million carats in response to a backlog of polished diamond inventories in the midstream and weaker trading conditions. The overall decline was mainly driven by reductions in Botswana (Debswana) and South Africa (DBCM). The miner's H1 production fell by 11% to 15.5 million carats from 17.5 million carats during the same period a year ago.

  • Rio Tinto's rough diamond production fell by 10% during the first half of the year despite improved output in the second quarter compared to the first three months of 2019. Production at its Argyle mine in Australia actually increased by 18% compared to Q1, but the nearly 3.3 million carats recovered in Q2 was 5% fewer than during the same period in 2018 due to lower recovered grade, partially offset by stronger mining rates. Output at the Argyle mine reached 6.1 million carats in H1 2019, a 13% decline compared to the same period last year.

  • Global rough-diamond production fell to 148.2 million carats in 2018, a decline of less than 2% from the 150.9 million carats recovered in 2017; however, a 4% rise in the average price per carat led to a 2.4% increase in the value of the world's rough diamond production, according to Kimberley Process (KP) data. Global diamond production was worth $14.47 billion in 2018 compared to $14.12 billion in 2017, as the average price per carat rose to $97.5 from $93.6. 

  • A mechanical breakdown and the mining of a lower grade area of the Liqhobong Diamond Mine in Lesotho led to a signficant production decline for Firestone Diamonds during the quarter ended 31 March 2019 (Q3 of tFY 2019), but revenue rose on a rebound in the average price per carat and the sale of high value stones.

  • De Beers Group reported a diamond production decline in the first quarter of 2019 driven by a 65 reduction in South Africa as the Venetia mine as it approaches the transition from open pit to underground mining. Venetia yielded only 0.4 million carats due to lower mined volumes, while the Voorspoed mine was placed onto care and maintenance in Q4 2018 in preparation for closure. De Beers' production guidance for 2019 remains unchanged at 31 - 33 million carats, subject to trading conditions.

  • Only weeks after recovering a 425-carat diamond, Petra Diamond's famed Cullinan mine has produced another big stone, this time a 209.9 carat D-Colour Type II diamond. The big diamond is the third +100ct Type II D color gem-quality diamond Petra has recovered since March 2019 and the fourth in this financial year. The find will take some of the sting out of the 7% production decline in the third fiscal quarter due to a slowdown at its Finsch mine in South Africa.

  • Despite a record year for the recovery of 'specials' (diamonds larger than 10.8 carats), including 33 diamonds in excess of 100 carats, Lucara Diamond earned its lowest revenue in six years due to the lowest average price per carat achieved in five years. Judging by their share prices, however, investors hardly seemed too concerned, as Lucara's stock price took an 8% dip following the announcement, only to regain half its loss back the next day.

  • According to new research published by the Fancy Color Research Foundation (FCRF), one of the most overlooked facts concerning the diamond industry is that the world’s diamond mines are rapidly depleting. Within a quarter of a century, the majority of the 45 most notable diamond mines operating today will cease to exist, and the last diamond will be unearthed in 60 years. According to the FCRF, diamond prices will rise as supply wanes.

  • "If even a fraction of Chinese production is upgraded to jewelry-quality diamonds, it would have a very significant impact on the global supply which is only in the low-millions-of-carats," independent diamond analyst Paul Zimnisky told Xinhua News journalists Wang Zichen and Shi Linjing.

  • Gem Diamonds had a banner year in terms of recoveries, sales and average prices acheived for its diamonds unearthed from its Letšeng mine in Lesotho. In addition to setting a company record for recoveries in a single year of diamonds larger than 100 carats (15) and of diamonds larger than 20 carats (257), in 2018 Gem's carats recovered increased by 13% to 126,875 carats (2017: 111 811 carats), sales jumped 29% to $267 million from $207 million, and the average price rose by 10% to $2,131 per carat, up 10% from $1,930 per carat in 2017.

  • Firestone Diamonds, a diamond producer with operations focused in Lesotho (Liqhobong Diamond Mine), reported "reasonsable" results in the quarter ended 31 December 2018 (Q2), increasing sales despite the "deterioration" in demand and prices for smaller, lower value stones. The miner sold 191,735 carats during the quarter, a slight decline from the 194,206 carats sold last quarter, realising revenue of $13.9 million (Q1: $13.5 million) at an average value of $72 per carat (Q1: $70 per carat).

  • South Africa-focused miner Petra Diamonds has seen its shares tumble 27% since Monday's announcement of its H1 2019 results, despite an 8% increase in sales and a 10% rise in production.  The culprit? Near-historical low prices earned from its rough diamonds from its flagship Cullinan mine. Prices achieved from the miner's Cullinan goods slumped 31% compared to last year, earning just $96 per carat, and compared to a nine-year average of $140 per carat from 2009 to 2018, the miner said. 

  • Multiple forces seem to be conspiring against the diamond industry these days, and if mining stocks are any indication, the wider market takes a pessimistic view of its prospects. But as independent analyst Paul Zimnisky explains in his latest analysis, "Don’t Give Up on the Diamond Industry Just Yet", to take this attitude as a foregone conclusion is to underestimate the resilience of the industry as a whole and overlook not only the enduring intangible value of diamonds, but also the impact of what may well become their much more tangible rarity.

  • Russian diamond mining giant Alrosa has announced its production results for 2018 and Q4 2018, reporting that annual production declined by 7% to 36.7 million carats, while an 8% decline in carats sold was offset by a higher average price per carat, leading revenues to rise 6% to $4.5 billion. The miner attributed the fall in output to the shutdown of the Mir underground mine and the completion of open-pit mining at the Udachnaya pipe.

  • The De Beers Group has announced its production results for 2018 and Q4 2018, reporting that annual production increased by nearly 7% to 35.3 million carats, while a 4% decline in carats sold was offset by a higher average price per carat, leading revenues to rise 2% to $5.4 billion. They said the rise is production was due to a planned increase at the Orapa mine, although the group's output was in the lower half of the production guidance range of 35 to 36 million carats.

  • Rio Tinto's diamond production for the year fell by 15% to 18.4 million carats from 21.6 million carats in 2017, as production at the Argyle mine in 2018 fell by 18% compared to 2017, when production was enhanced by the processing of higher grade alluvial tailings. The fourth quarter in particular put a drag on the annual figures, as the 3.2 million carats unearthed represented a 48% decline from Q4 2017 - albeit against a high base of 7.21 million carats - and a 16% decline from last quarter.

  • Lucapa Diamond Company has commenced commercial diamond recoveries at its new 1.1Mtpa (million tons per annum) Mothae mine, a "high-quality kimberlite resource" located in Lesotho. Lucapa has been developing a new mine at Mothae throughout 2018 to complement production from the high-value Lulo mine in Angola. During Q4 2018, Lucapa completed construction of Mothae's new treatment plant, which incorporates two XRT diamond recovery circuits, and commenced the commissioning phase.

  • Diamond production in Angola remained flat in 2018 at 9.43 million carats, but revenue from diamond sales increased by 9% to $1.2 billion from $1.1 billion due to a 27% rise in the average price per carat, the chairman of the state mining company Endiama, Ganga Júnior, announced this week. Diamond production fell slightly from 9.44 to 9.43 million carats, but the average price per carat of the 8.26 million carats sold increased to $149 per carat from $117 per carat.

Output is then expected rise to a range of 6.6 million to 6.9 million carats in each of 2019 and 2020, followed by 6.8 million to 7.1 million carats in 2021. The miner says the production guidance over the three-year period 2019 to 2021 is evidence of a sustainable and smooth mining rate as the mine performance maintains a steady state.

  • Canadian miner Mountain Province's production and sales of rough diamonds from the Gahcho Kué mine underwhelmed in the third quarter of 2018, as production was on the downside of flat during the quarter, while sales increased against a low comparison point in 2017 and the cost of production rose. Sales increased by 15% to US$57 million (C$75 million) at an average price of US$73 per carat, but net income dropped by 37% to US$13 million (C$17.5m) from US$21million (C$16m).

  • Lucara Diamond Corp.'s third quarter carat production from its Karowe mine in Botswana "exceeded expectations" as a result of increased efficiency in diamond recovery in the smaller sizes during 2018.

  • The Zimbabwe Consolidated Diamond Company (ZCDC), according to a column written by President Mnangagwa in The Sunday Mail, that the country's diamond output was expected to shatter previous records. Zimbabwe aims to produce (at a stretch) three million carats this year, driven by a US$100 million investment in operations over the last two years.
