ZCDC diamond guards accused of cold blooded murder of citizens
Security guards working for the government-owned Zimbabwe Consolidated Diamond Company (ZCDC) have killed “scores of citizens in cold blood,” according to a coalition of Zimbabwean civil society organizations.They also accuse the ZCDC of torturing artisanal diamond miners in the Marange diamond fields, as a punishment for alleged illegal mining.
Eight groups, including the National Mine Workers Union of Zimbabwe, Zimbabwe Artisanal Miners Association and Zimbabwe Diamond Workers Union call on ZCDC to publicly acknowledge their culpability in Mutindindi’s death.
They make a series of additional demands, that includes sending all ZCDC security personnel for human rights training, and conducting a voluntary human rights audit to understand the extent and nature of ZCDC human rights violations.The ZCDC started operations in February 2016 as part of a government initiative aimed at enhancing transparency and accountability in the diamond sector.
In 2023 the US sanctioned Zimbabwe’s President Emmerson Mnangagwa for human rights abuses, corruption and smuggling gold and diamonds.Mnangagwa, 81, who has held office since 2017, insists the claims against him are “defamatory” and “malicious”.

CVD Synthetic Fashioned To Imitate A Rough Natural Diamond
The Near-Colorless Stone Is Believed To Be The First Time Creators Of A Synthetic Chemical Vapor Deposition (CVD) Diamond Have Shaped It To Resemble A Rough Diamond
The 6.87-carat near-colorless CVD diamond was shaped to resemble a natural rough octahedral crystal but showed distinct synthetic features under microscopic and spectroscopic analysis.GIA’s tests confirmed the stone’s synthetic origin, noting polishing marks, facet junction roughness, and luminescence patterns inconsistent with natural diamonds.
No evidence currently suggests widespread substitution of synthetics for rough natural diamonds, but existing detection tools could be adapted if such cases increase.
The near-colorless stone is believed to be the first time creators of a synthetic chemical vapor deposition (CVD) diamond have shaped it to resemble a rough diamond, according to an article in the spring issue of the institute’s Gems & Gemology quarterly journal.
Upon investigation with the use of raman spectroscopy, the results confirmed that the material was a diamond, with its near-octahedral shape similar to that of a natural rough crystal. Further analysis showed that it was not a true octahedron, as only one set of opposing faces was parallel. Microscopic observation under differential interference contrast revealed extremely flat faces marked mainly by parallel polishing lines, unlike the growth steps and trigons typically seen on natural octahedral faces. The facet junctions were extremely rough, possibly due to measures taken to improve the color, after which the main faces appear to have been repolished, the institute explained.
