SkyDiamond, a British company that uses carbon capture to create rough diamonds, has appointed Madeleine Macey as its first CEO. Macey was most recently chief marketing officer of Liberty and has spent more than 20 years working in communications and marketing roles at fashion and luxury goods companies. She joined SkyDiamond in September and reports to Asif Rehmanwala, CEO of the Green Britain Group, which houses Vince’s businesses. Macey said her aim is to take the diamonds further into the luxury sphere, following the collaborations with Stephen Webster, Bleue Burnham for Gucci Vault, and Selfridges.
