Pavel Vinikhin: ALROSA will make a worthy contribution to the revival of the ‘Russian Cut’ Brand

16 october 2017

ALROSA is known as the largest diamond mining company throughout the world. However, not everyone is aware that it has its own diamond-cutting division. For a long time, the activity of DIAMONDS ALROSA remained in the shadows, only occasionally attracting the attention of journalists. However, recently the Dynasty, a unique diamond collection produced by DIAMONDS ALROSA, was sensationally presented first in Moscow, then at the Eastern Economic Forum in Vladivostok and later in Hong Kong. The collection, which already created a great deal of excitement, will be put up for sale in November at an online auction based on ALROSA's own IT platform. Pavel Vinikhin, Director of DIAMONDS ALROSA told Rough & Polished about the work on the collection, prospects of its international tour and plans for further development of the diamond cutting business he runs.

William Lamb: Lucara now knows best routes to market large stones

09 october 2017

Lucara Diamond recently announced that Graff Diamonds had bought its 1,109 carat diamond Lesedi La Rona for $53 million. The stone, which is the world’s second largest diamond found since the discovery of the 3,106-carat Cullinan diamond in 1905, failed to find a buyer at a public auction in London on 29 June, 2016 and the company vowed not to auction the diamond again. Reports suggested that the stone had a reserve price of $70 million, but bidding stalled at $61 million. Lucara had, however, partnered with Nemesis International DMCC a month prior to the London auction and sold its 813 carat diamond – named “The Constellation” – for $63,1 million. Company chief executive William Lamb told Rough & Polished’s Mathew Nyaungwa that one shouldn’t fall into the trap of comparing the revenue accrued from the sale of both stones. He said what was significant was the fact that the stones were collectively sold for almost the same amount as the cost of building Karowe Mine, in Botswana. The diamonds originated from the south lobe of Karowe Mine. Lamb admitted that they had had some learning to do on the best way to market large diamonds. Below are excerpts from the interview.

‘There is no illegal tanzanite mining in Tanzania’

28 august 2017

Richland Resources, which wholly-owned TanzaniteOne until the Tanzanian government forced it to relinquish half of its stake to the State Mining Corporation (STAMICO), exited the country in 2015 to focus on its operations in Australia. The formalisation of the JV with Stamico in December 2013 saw Richland receiving assurances that illegal miners in Block C would be removed, allowing reinvestment in the mining infrastructure and consequently improve output. However, owing to what Richland called “government inaction”, they continued to experience interruptions in most of the undersigned mining areas in the mining licence area. Before its departure, the company bemoaned a “significant” increase in illegal underground mining at its then joint venture tanzanite operation. It said illegal miners were entering underground areas from neighbouring blocks posing danger to its employees. But, local dealers don’t see any problem of illegal tanzanite mining in the country as suggested by Richland. Begoti Enterprises marketing manager Bahati Mollel told Rough & Polished that Richland’s claims of illegal mining was a ruse and their eventual departure of the country was because they had “harvested” enough. He also commented on challenges they are facing in marketing cut and polished tanzanite. Mollel, however, posited that there was need for locals to meet international standards to ensure penetration of international polished markets of their stones.
