The 19 Richest Diamond Owners in the World

Diamond formations occur over millions of years deep in the Earth’s crust. And because only a minute percentage of diamonds mined are considered to be of gemstone quality, they are considered relatively rare and, thus, valuable. In fact, pure, natural diamonds have long established a consistent value by maintaining a relatively standardized benchmark or threshold price – like the precious metals of gold and silver.

While the economy’s overall health has some influence on diamond prices, this precious gemstone has consistently gained value over the years - about 14% per year since 1960! And, with continued global economic growth, the rising demand for luxury goods, and a decrease in diamond mining, the market price for gem-quality natural diamonds is anticipated to move in an upward direction.
