Invest in Pink Diamonds

  • The demand for pink diamonds has exceeded available global supply, which may lead to dramatic price increases upon the mine's closure.
  • The Argyle mine is expected to run its course by 2021 until new sources can be found.
  • Despite producing 90 per cent of the world's pink diamonds, the mine's total production of pinks is less than 1 per cent.
  • All of the diamonds submitted for testing at the Gemological Institute of America (GIA) each year (fewer than 0.02) per cent are predominantly pink.
  • Over the past decade, pink diamond prices increase by 10-15 per cent each year.


The diamond is the hardest naturally occurring mineral and one of the most beautiful gemstones on earth. Mines across the world produce more than 100 million carats of diamonds annually. Australia is one of the biggest producers of diamond gemstones, accounting for 210 million carats in production. Three global diamond mining companies control more than half of global diamond production. British-Australian mining company Rio Tinto is one of these companies. The company owns Argyle mine, where over 90% of the world’s yearly supply of natural pink diamonds is sourced. The Argyle Diamond Mine also holds the monopoly of violet, red, and champagne coloured diamonds. Rio Tinto’s Argyle Diamond Mine will cease operating by early 2021. Like all assets, the diamond market follows the laws of supply and demand. As such, when Argyle mine does close, the supply of pink diamonds will further decline. This presents the perfect opportunity for investors to make huge returns in the medium term. Start you pink diamond investment while diamond prices are still stable. In a few years' time, you can sell your rare Argyle pink for several times the price of a regular colourless diamond.


Before buying a diamond, you must have a clear understanding of how it is priced. First, every diamond investor should understand that there is no globally approved per gram pricing for diamonds. Diamonds are sold per carat on average. To get the total diamond price, multiply the price per carat by the carat weight. This means purchasing diamonds with bigger carats would cost you more than purchasing smaller ones. Price increases when supply drops while demand for a particular diamond continues to rise. Colour, clarity, cut (proportions) and density may also affect its price. Diamonds with visible tints or colours are generally considered flawed. They may fetch a lower market price than clearer stones with little to no visible tints. Cleanly cut round-shaped or princess-shaped diamonds are buyer favourites and tend to be more pricey per market standards.


Individuals have different reasons for collecting diamonds. Perhaps you believe diamonds are forever and make for a good investment. Or you need diamonds to add extra brilliance to a special moment in your life. Collector diamonds, on one hand, appeal to a niche market that purposely acquires rare gems for future investment or for posterity's sake. These individuals invest in exclusive diamonds and purchase them as assets, seeking high return on investment.
