Diamond prices recorded an average growth of about 14% per year over more than half a century (1960 - 2016). This sustainable growth was maintained thanks to De Beers' monopoly supply control strategy, marketing campaigns that turned diamonds into a symbol of eternal love, and their characteristic as an effective inflation "hedge."

Diamond prices in the period 1960 – 1980
The 1960s marked a turning point when De Beers collaborated with N.W. Ayer to carry out a campaign making diamonds a symbol of marriage.
- In 1960: The price reached about 2,700 USD/Carat. Demand in the United States surged by 55%.
- The 1970s: As inflation and recession loomed, diamonds became a target for investors seeking to preserve capital. By 1970, prices had reached 6,900 USD/Carat.
- In 1980: Prices rose sharply to 10,500 USD/Carat. This was the period when diamonds established their position as the most steadily appreciating tangible asset.
Period 1980 – 2000
During this period, the market began to see new changes as major diamond mines outside the De Beers system appeared.
- Market share changes: De Beers declined from 90% to 80% by the end of the 1990s.
- Growth rate: Diamond prices increased slightly from 10,500 USD to 13,900 USD/Carat. As the market became more flexible, the increase was no longer as sudden as before, but still maintained a steady upward trend.

Why are diamonds always a smart investment channel?
History has proven that even when the financial market collapses (such as in 2008), diamonds only fell by about 12% – a "gentle" figure compared to the chaos of real estate or stocks. With policies controlling sales volumes below production volumes, major corporations always ensure that diamonds never fall into a situation of excess supply, thereby protecting value for long-term investors.
