D.Louise was founded in 2021 by Olivia Jenkins, who named the direct-to-consumer jewellery brand after her late mother, Deborah Louise. Olivia co-founded the business with serial entrepreneur Jack Zambakides and former professional cricket player Oliver Smithson. The South London company has gained attention for its high-quality, waterproof jewellery made from stainless steel, designed to withstand daily wear without tarnishing. In 2023, D.Louise received investment from Steve Hewitt, former chief executive of Gymshark, to help facilitate the brand’s international expansion. In March 2024, Olivia completed a 313km charity walk from Cardiff to Wandsworth in memory of her mother.
