Diamond Prices: Have They Increased or Decreased Over the Last 10 Years, and What Are the Forecasts for the Future?

The diamond market has always been a symbol of luxury and rarity, but its economic evolution over the past decade reveals a complex dynamic influenced by economic, technological, and social factors. So, have diamond prices gone up or down? And what do experts predict for the coming years?

Retrospective: Diamond Price Trends Over the Last 10 Years

1. Price Stability and Fluctuations

Between 2010 and 2015, diamond prices showed relative stability, supported by strong demand in emerging markets such as China and India. However, from 2015 to 2020, there was an overall decline due to several factors:

• An increase in the supply of rough diamonds, particularly with the opening of production in new mines.

• A decrease in demand in Western markets, especially among younger consumers who prefer other forms of investment or consumption.

• The emergence of synthetic diamonds, which offer a more affordable alternative.

2. The Impact of COVID-19 on the Market

In 2020, the pandemic caused a sharp drop in global demand for diamonds, leading to a decrease in prices. However, the economic recovery in 2021 and 2022 fueled a rebound, especially for high-quality, large diamonds, driven by strong post-pandemic demand.

3. Synthetic Diamonds: A Disruptive Factor

The growing popularity of lab-created diamonds has played a significant role in the downward pressure on natural diamond prices. Their much lower cost and ethical appeal attract an increasing number of consumers, eroding the perceived value of natural diamonds.

Forecasts: What to Expect in the Coming Years

1. Upward and Downward Trends

According to experts, the future of diamond prices will be marked by increasing polarization:

• High-quality natural diamonds: These stones, particularly rare (D–F, IF–VVS), are expected to maintain a high value—if not increase—due to declining global supply. Some iconic mines, such as the Argyle mine in Australia, have ceased production, reducing overall availability.

• Synthetic diamonds: Prices are expected to continue falling thanks to technological advancements in production and growing public adoption.

2. The Impact of Sustainability and Ethics

Consumers, especially younger generations, place increasing importance on ethical sourcing and environmental impact. This may accelerate demand for synthetic diamonds and push the natural diamond industry to adopt more responsible practices.

3. Investment and Speculation

High-value natural diamonds will continue to be considered a stable form of investment, similar to gold. During periods of economic instability, investors may turn more heavily to these assets, thereby boosting demand.

Conclusion: A Market in Constant Transformation

The diamond market is undergoing significant change. Although natural diamond prices have experienced fluctuations over the past decade, their growing rarity may support price increases in certain segments. Conversely, the rise of synthetic diamonds is reshaping consumer expectations and pushing the industry to innovate. The future of the market lies in its ability to balance luxury, ethics, and accessibility to meet evolving consumer needs.
