Australian pink diamonds are extremely rare, making up less than 0.1% of all diamonds mined. The most famous source, the Argyle mine, closed in 2020 after about 30 years of operation, which has permanently reduced the supply of these stunning gems. This rarity significantly enhances their diamond valuation, making Australian pink diamonds a potentially lucrative investment. Over the past three decades, the prices for premium Argyle certified pink diamonds have increased by an average of 28% per year, showcasing their strong investment value.
Unlike other commodities, Australian pink diamonds are not subject to the same economic volatility. According to a report by the Natural Diamond Council (NDC), the estimated wholesale value of fancy color diamonds entering the market in 2024 surpassed USD 4.5 billion. The report, citing data from the Fancy Color Research Foundation (FCRF), highlights that prices for these rare gems, including Australian pink diamonds, have appreciated at a compound annual growth rate of 5.7% over the past two decades. This trend underscores the continued strength and investment value of the fancy color diamond market.
Australian pink diamonds are tangible assets due to their physical nature, finite supply, and independent value. They have historically proven to be effective stores of wealth, combining beauty, rarity, and financial resilience, which enhances their investment value and supports accurate diamond valuation.
The valuation of Australian pink diamonds is tracked through multiple credible platforms and reports:
Fancy Color Research Foundation (FCRF) – issues quarterly price indexes based on real transaction data for diamond valuation.
Rapaport Price List & Rapaport Magazine – publishes data and market analyses for both colorless and fancy-colored diamonds, providing insights into their investment value.
Natural Diamond Council (NDC) and Bonhams / Sotheby’s / Christie’s auction results – offer historical benchmarks and records for investment-grade stones, including Australian pink diamonds.
Pink diamonds, especially the rare Australian pink diamonds, have consistently fetched high prices at auctions. The Pink Legacy, an 18.96-carat Fancy Vivid Pink (VS1), sold at Christie’s Geneva in 2018 for CHF 50.375 million (≈ US$50 million). This sale exemplifies the significant diamond valuation associated with these precious stones. Similarly, the Sweet Josephine, a 16.08-carat Fancy Vivid Pink cushion-cut diamond, sold at Christie’s Geneva in 2015 for US$28.5 million. Another remarkable example is the Graff Pink, a 24.78-carat Fancy Intense Pink emerald-cut diamond, which sold at Sotheby’s Geneva in 2010 for US$46 million, highlighting its impressive investment value.
Australian pink diamonds, perhaps better than any other hard asset or supposed safe haven, have always been a great way for astute investors to shelter their portfolio from the storms in financial markets, thanks to their strong diamond valuation and investment value.
