Why Invest?

Historic Performance

Pink coloured diamonds have outperformed all other asset classes over the last 10 years, with an average 13.8% growth per year.

Supply and Demand

With the closure of the Argyle mine scheduled for 2021, which supplies 90% of the world’s pink diamonds, and ever increasing demand from Asian markets, price increases are being driven up as global supply moves towards exhaustion.


Pink coloured diamonds can act as an important part of a balanced investment portfolio, offering low correlation and insulation from traditional financial market risks.

How it works

The investment process simplified

The process of investing can be a daunting prospect for those not familiar with diamond investments. We break down every aspect from how to acquire a diamond, to certification, valuation, storage, insurance and eventual sale.

At Australian Diamond Portfolio we are able to handle every step of this process for you.

What to buy

Finding the right diamond for you

When selecting the right diamond, many factors need to be taken into consideration, such as budget, duration of investment and the investment vehicle you chose to invest with. Coloured diamonds have different value factors compared to regular clear diamonds and each colour and size has its own performance history.

Diamond Grading & Value

How is the value of a diamond determined

How is the value of diamonds determined? With coloured diamonds the value is determined by the rarity and beauty of the colour.
