Australian Pink Diamonds

The Rarest of all Diamonds

The story of the Australian pink diamond is almost as captivating as the rare gem itself. Across the breadth of 1.6 billion years, on a journey from the Earth’s centre, the most intriguing diamond in history emerges from a Western Australian pink diamond mine, with an exquisite beauty that is both regal and mesmerizing. A pink diamond’s spectacular outback origin can be seen in this marvel that explores every shade of the desert sunset – from a soft rose, a cherry blossom pink, a mystical violet to a deep dramatic red.

Argyle pink diamond investment

Pink diamonds from the Argyle are beautiful expressions of the hardworking history of the Argyle Mine in Western Australia. Dazzlingly elegant, the pink hue of an Argyle pink diamond denotes its rarity — only one in one million carats of rough diamonds that the Argyle Mine has produced are pink. But why invest? It is important to have a diversified portfolio in this day and age, and Argyle pink diamonds are the right way to invest with confidence — and Argyle Diamond Investments is here to help.

  • Quality

Argyle diamonds are not just aesthetically pleasing; they are incredibly durable due to their authenticity. The durability of the Argyle certified pink diamonds that we specialise in is one of their greatest qualities. As the hardest stone on earth, you can be confident that your investment will not depreciate simply from staying in storage or even during everyday use. Another distinctive feature of the diamond is its small size. Due to this combination of durability and size, you can safely store large quantities of them in a safe or even wear them wherever you like.

  • Demand

Due to these diamonds’ rarity, durability, and beauty, there is an ever-increasing demand for Argyle certified Pink diamonds in the market. As there is no other comparable known source for the production of Argyle certified pink diamonds anywhere in the world, the supply is heavily outweighed by the demand. The closure of the Argyle Mine in 2020 has ensured that the rarity of these diamonds will only increase. This is a uniquely rare commodity. The potential for wealth preservation through tangible investment in Argyle certified pink diamonds is astronomical. There is a reason that SMSF investors are so interested in Argyle certified pink diamonds — increasing prices and low volatility. When you invest in Argyle certified pink diamonds, you are investing in a high-quality item that will stay reliably safe for years to come.

  • Authenticity

Argyle Diamond Investments takes the authenticity of Argyle pink diamonds very seriously. We only acquire natural Australian Argyle pink diamonds with Australian Argyle diamond certification declaring their source and authenticity.


Argyle Diamond Investments works diligently to ensure the proper grading of every product we handle and distribute:

  • Argyle Provenance certificate — This Argyle issued essential certificate ensures the authenticity of all Argyle pink diamonds in Australia. It tracks the process from mine to market to give you the confidence that you need when investing in Argyle certified pink diamonds.

Hi my name is David and I have given permission to ADI to share this.

I am a former superannuation advisor and financial planner*, and I would like to share my Argyle experience. In early 2019 I started becoming concerned about my ability to negate some of the volatility that was occurring within the share market and directly effecting my self-managed super fund. I started to look to alternative investments in order to diversify my assets. After several months of research, I purchased some gold and my first Argyle diamond, in order to secure a small proportion of the fund in hard assets. I took a small profit on the gold and continued to explore investment quality Argyle diamonds. This was when I first contacted ADI. At this stage I knew my first purchase was a good one however, if I was going to be a serious investor in this area, I need an industry relationship, not just a retailer. I.e., There is no point holding assets that may appreciate in time in an unregulated market if you have no ability to track the market, or dispose of the asset at a time of your choosing. ADI provided this at every step. Since late 2019, I have purchased 4 more Argyle diamonds at wholesale prices, including a match found for the one I already held to make up a pair. This makes up a significant proportion of my SMSF. With the mine now closed and supply gone I indicated to ADI that I was happy to sell one of my Argyles at the right price if they had a buyer. A fortnight ago ADI contacted me to see if I was still prepared to part with one of my holdings as they had had a request. ADI managed the sale and after they received my secured delivery, the money went into my SMSF the next day. Seamless. I made a significant profit, especially as I had only held the diamond for just over 18 months. I still hold my matching pair and my two larger diamonds including a blue, and will continue to do so. However, it is so good to know that when I do want to realise my capital gain, I have such a great team to help me do so.

Kind Regards
