Introducing the Argyle Mine
Over 90% of the world’s annual natural pink diamond supply is 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 is scheduled to completely cease all mining operations by 2021 due to exhausted supply.
In anticipation of this closure date, investors buying pink diamonds are seeing an average appreciation of between 10-15% on their diamond portfolios each year.
Pink coloured diamonds can act as an important part of a balanced investment portfolio, offering low correlation and insulation from traditional financial market risks.
