The primary investment appeal of Australian pink diamonds is their potential for capital gain. Over the past decade and more, anyone that has purchased an Australian pink diamond has seen a significant appreciation in the value on their investment. Strong performance is not limited to the last decade, with pink diamonds delivering exceptional returns over the last 20 years.

Pink diamonds have outperformed all major asset classes and commodities and have shown very good stability and consistency of performance over the long-term and been considered an important holding for strategic investors. Since formal records regarding diamond pricing were first kept at the beginning of the 1970’s, prices for pink diamonds have appreciated between 10% to 20% per year on average across all sizes and categories.

Over 95% of the world’s annual natural pink diamond supply was mined from one single source: Rio Tinto’s Argyle Mine in Western Australia. The mine has been in operation since the early 1980’s and in November 2020 ceased all mining operations. The mine has been the most significant source of rare pink diamonds producing more than 90%-95% of the world’s supply.

The closure of Rio Tinto’s Argyle Diamond Mine is a major milestone and its significance has not been lost on savvy investors. Like all assets, the diamond market follows the laws of supply and demand and the supply of pink diamonds will now be even more limited. This closure positions the pink diamond as an investment opportunity offering significant capital gains in the medium to long term.
