A Diamond is Forever: An Analysis of De Beers' Marketing Strategies and Their Influence on Market Participants’ Purchasing Behaviour

This paper analyses the enduring success of De Beers in the global diamond market by analysing its marketing strategies through the lens of consumer behaviour theories. By applying models such as Brand Positioning and Maslow's Hierarchy of Needs, the paper explores how De Beers has effectively transformed diamonds from rare commodities into powerful symbols of love, status, and personal milestones. It critically examines the company’s ability to create deep emotional connections with its target consumers, primarily through its iconic "A Diamond is Forever" campaign, while also considering the challenges posed by the rise of synthetic diamonds and shifting consumer demands for sustainability and ethical sourcing. The paper concludes with strategic recommendations for De Beers to maintain its market leadership, including embracing digital innovation, enhancing ethical transparency, and cultivating inclusivity in its brand messaging to meet the evolving expectations of modern luxury consumers.
