Rare coloured diamonds have strong long-term returns

The primary investment appeal of rare coloured diamonds stems from their long-term history of strong, stable gains.

This is particularly true for the three most traded categories of coloured diamonds recognised for their investment appeal: yellow diamonds, blue diamonds, and most notably pink diamonds. Since 1970, natural blue diamonds have doubled in price every 5 years, pink diamonds have doubled in price every 6-7 years, and fancy yellow diamonds have doubled in value every 8 to 10 years.

Below is a snapshot depicting the strong returns of these coloured diamonds relative to other traditional asset classes, since 2005.
