The realisation that the supply of these truly rare diamonds would soon cease to exist outside of the secondary market made its impact with a surge in demand for these natural treasures. With the supply of Argyle certified diamonds dwindling, jewelers and diamond brokers are now resorting to selling inferior GIA certified non-Argyle and Argyle-origin pink diamonds as a supposed investment, in order to financially capitalize on the closure of the Argyle mine. This is potentially motivated-misdirection or at best, pure inexperience on their behalf. Regardless of how many creative stories you will hear about the possibility of these diamonds growing in value after the Argyle mine closes, the FACT is that certified non-Argyle and Argyle-origin pink diamonds are considered inferior as an investment option.

Argyle Diamond Investments with years of experience has delved into the various aspects of investing in pink diamonds and consider it essential to look at your investment’s ability to grow based on several key areas included in this publication. Exploring these topics will illuminate why Argyle certified pink diamonds are growing in value at an astonishing rate and why GIA certified non-Argyle pink diamonds have stagnated in value.

Pink Diamond Sizes

When purchasing an Argyle certified pink diamond, statistically, most people fall into two classifications, ‘the investor and the collector’. Regrettably, a great deal of people think they are buying an investment pink diamond but end up buying a collectable pink diamond instead.

An Argyle investment pink diamond is commonly identified as being “substantial and rare”. These quality larger sized, low volume pink diamonds will always remain calm through market volatility because of their strong demand from the Asian and American jewellery markets. Historically only 9.66% of all pink diamonds from the Argyle mine are 0.20ct or larger in size and as per end of year 2018 to 2019 only 8.91% where 0.20ct or larger. Over the next few years, it is expected up to 50% of these already rare larger sized diamonds will end up set into jewellery and will only re-emerge on the global market through a divorce or deceased estate. This makes a 0.20ct plus size even more rare by volume.

Argyle collectable pink diamonds are commonly identified as being “pretty and precious” because of their smaller sizes. Unfortunately, due to their abundant numbers and lack of rarity, these smaller diamonds don’t attract the same Argyle quarterly allocation price increases and have a lower global demand compared to the larger and rarer Argyle certified pinks. Statistically 90.34% of all pink diamonds from the Argyle mine fall in the 0.01ct to 0.19ct weight group. Therefore, the secondary market price for these collectable pink diamonds will purely be based on the rarity / volume available on the market at any one time. These pink diamonds are also generally too small to be set in a single stone item of jewellery, causing the Asian and American markets to avoid these sizes. It seems size is a dominating factor for these countries, as they like to see the money.


There are numerous key factors to consider when purchasing a pink diamond for a maximum investment return. By understanding the factors unique to selecting a coloured diamond, purchasing the right pink diamond will allow you to reach your goals sooner.

In most cases, the sale of your diamonds will be at wholesale prices, usually through an auction house or retail jeweller. By securing your investment for the same price a jeweller would pay – and not an inflated retail price – you can minimise the time required to see a return profit on your diamond investment.

Currently the demand for rare Argyle pink diamonds outweighs the supply as only a select number of these are retained and polished by the Argyle mine. Failing to meet Argyle standards, the remainder are sent to auction to be sold as seconds, cut and polished in house by the jewellers that purchase them. These gems will seldom have an Argyle Certificate, which is the description of the unique characteristics of the diamond based on the proprietary grading techniques of Argyle. The stronger the provenance to the Argyle brand the higher your financial return.
