Chairman and chief executive Vashi Dominguez, 41, set up this online diamond sales platform in 2007. It made the jump to bricks and mortar in 2016 and its six shops now contribute about 40% of its revenue. They are designed to be laid-back and fun, with workshops where customers can have their rings personalised by craftsmen. Profits rose to £6.9m in 2018 and the firm has ambitions to expand into Asia. It has temporarily closed its stores but customers can still design jewellery online for delivery.
