Diamonds Are Not Actually Rare

The perception of a diamond's value is a fascinating intersection of geology, economics, and marketing. Geologically, diamonds are more common than many other precious gems, formed deep within the Earth's mantle and brought to the surface through volcanic pipes. While high-quality, jewelry-grade diamonds are less common than industrial-grade stones, diamonds as a mineral are relatively plentiful compared to gems like emeralds and rubies. There are an estimated quadrillion tons of diamonds deep within the Earth, though they are not accessible.

The high price tag on diamonds is largely a result of strategic market control. For much of the 20th century, the De Beers company established a monopoly, at its peak controlling 80% to 90% of the world's rough diamond distribution. This allowed the company to stockpile diamonds and limit the supply available on the market, creating an artificial scarcity to keep prices high. This illusion of rarity was crucial in establishing the gem's prestige and high value in the public eye.

This economic control was solidified by one of history's most influential advertising campaigns. In 1947, De Beers introduced the slogan "A Diamond is Forever," which masterfully linked the stone's durability with the concept of eternal love. The campaign successfully manufactured the tradition of diamond engagement rings, transforming the gem into a cultural symbol of commitment. This marketing effort, which also suggested men spend one to two months' salary on a ring, cemented the high price of diamonds not based on their actual abundance, but on their newly created cultural significance.
