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.
