De Beers: Reverse-Disrupting the Diamond Industry

Set in September 2018, the case describes De Beers’ attempt to halt the escalating disruption to its core business posed by diamonds grown in laboratories. Since its inception over a century ago, De Beers had created and nurtured the perception of diamonds as rare objects and exclusive symbols of love. But lab-grown diamond makers now had the capabilities to mass-produce and sell at a discount diamonds with the same optical, chemical and physical characteristics as natural ones, possibly jeopardising the entire mined-diamond industry. To counter the threat, De Beers introduced its own lab-grown diamond jewellery brand, called Lightbox. Lightbox diamonds were positioned as cheerful fashion items and sold directly to consumers at a substantial discount to generic lab-grown diamonds. Over its history, De Beers had had a remarkable track record of dwarfing competition. Would it succeed this time?
