Sally Morrison, the head of marketing for Lightbox (De Beers' synthetic stone brand), said the brand's products were meant to be viewed by consumers as playful accessories. "Everyone who is in this space is focusing their marketing on the bridal category," Ms. Morrison said. "And we believe they are missing an incredibly interesting opportunity: the self-purchasing professional and younger woman, the older woman who already has a jewelry collection," and any woman "who doesn't want the weight and seriousness of a real diamond for everyday life." "Though man-made stones account for only about 2 percent of the diamond industry's supply, analysts at Citibank have forecast a possible rise to 10 percent by 2030."
