Diamonds were too rare and expensive for those of lesser means to afford until the discovery of African diamond mines in the 1870s. The De Beers Company was the sole owner and operator of these newly discovered mines in South Africa. In the 1930s, when demand for diamond rings declined in the U.S. during hard economic times, the De Beers Company began an aggressive marketing campaign using photographs of glamorous movie stars swathed in diamonds. Within three years, the sales of diamonds had increased by 50 percent.
