Thanks to a stint as digital content editor of Forevermark, diamonds are now one of my specialist subjects. Projects included copy management of the Forevermark app, produced by AKQA, which launched on iTunes in 2011.

Forevermark sponsored the re-presentation of the Crown Jewels in 2012. This was a gift in terms of content creation but it did present a challenge – we did not have permission to use imagery of the Crown Jewels themselves. What we did have, however, was a life size model of the Cullinan Diamond (whose famous stones appear in the Imperial State Crown and the Sovereign’s Sceptre with Cross) – and an in-house expert who was able to show us how it was cut.
