How do you build a luxury jewellery brand from nothing? Jewellery designer Hannah Martin (Central Saint Martins, Cartier Paris) reveals how she built her independent fine jewellery business over 20 years — surviving near-bankruptcy, a business partner betrayal, and building a cult luxury brand without investors.In this episode of Runway to Excellence, the luxury fashion and jewellery industry podcast from SJR London, host Stephanie Jackson sits down with Hannah Martin, the iconoclastic British jewellery designer who trained at Central Saint Martins, won a scholarship into the high jewellery department at Cartier Place Vendôme in Paris, and walked away to launch Hannah Martin London — a bold, gender-fluid fine jewellery brand designed to make your heart beat faster.Hannah shares the real story of starting a jewellery business with no money: sending DIY lookbooks to fashion editors, the business partner who signed 50% of her shares to himself and nearly destroyed the company, and how she rebuilt to create one of the most loved independent luxury brands in the UK. From designing jewellery for musicians and Wayne McGregor's dancers to getting her pieces on Lola Young at the Brit Awards without a PR agency — this is a masterclass in creative entrepreneurship, luxury branding, resilience, and playing the long game in business.We also discuss Hannah's book, Iconoclast — a 20-year retrospective for the creatives, dreamers, and rule breakers — available at hannahmartinlondon.com.This podcast is brought to you by SJR London, the trusted talent partner for Luxury Fashion, Beauty and Lifestyle recruitment.
