On March 19, 2025, the Natural Diamond Council (NDC), in collaboration with the High Commission of Canada in the UK and the Government of the Northwest Territories, hosted the prestigious “Diamonds, A Canadian Love Story” event at Canada House, Trafalgar Square, London. This exclusive gathering showcased the ethical sourcing, cultural heritage, and global influence of Canada’s natural diamonds, with a special focus on their positive impact on Indigenous communities and the fine jewellery industry.
Canada is renowned as one of the world’s leading sources of ethically mined diamonds, and the event celebrated the country’s commitment to responsible practices in the diamond industry. Key figures in the sector gathered to discuss the role of Canadian diamonds in the future of luxury jewellery.
A highlight of the evening was an insightful panel discussion moderated by Bronwyn Cosgrave, celebrated author and producer. The panel featured Lily James, Emmy-nominated actress and Global Ambassador for the Natural Diamond Council; Kateri Rose Lynn, Councillor of Dettah – Yellowknives Dene First Nation and representative of Diamond de Canada; Paul Gruner, CEO of Tłı̨chǫ Investment Corporation; and Jody Wainwright, Managing Director at Boodles.

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.
