These rare gems, mined exclusively from the Argyle mine in Western Australia, represent a unique opportunity for investors seeking both aesthetic and financial returns. As we delve into the specifics of investing in pink Argyle diamonds, we will explore their origins, the factors that influence their value, and strategies for maximizing your investment.

The Origin and Rarity of Pink Argyle Diamonds

Pink Argyle diamonds are among the rarest and most sought-after gemstones in the world. The Argyle mine, operated by Rio Tinto, has been the primary source of these exquisite diamonds since its discovery in 1983. This mine produces over 90% of the world’s supply of pink diamonds, making its impending closure in 2020 a significant event in the diamond market. The rarity of pink Argyle diamonds is underscored by the fact that less than 0.01% of the diamonds mined at Argyle are pink.

Unique Characteristics of Pink Argyle Diamonds

The distinctiveness of pink Argyle diamonds extends beyond their rarity. These diamonds are renowned for their:

Exceptional Color: The intensity and saturation of the pink hue in Argyle diamonds are unmatched. The color range includes shades from delicate pastel pinks to deep, vivid pinks.

Unique Grading System: The Argyle mine uses a proprietary color grading system, which classifies pink diamonds into categories such as PP (Purplish Pink), P (Pink), PR (Pink Rose), and PC (Pink Champagne).

Provenance: Each pink Argyle diamond is accompanied by a certificate of authenticity, ensuring its origin and adding to its investment appeal.

Factors Influencing the Value of Pink Argyle Diamonds

Investing in pink Argyle diamonds requires a thorough understanding of the various factors that influence their value. These factors include color, clarity, cut, and carat weight, each playing a crucial role in determining the overall worth of the diamond.


The most critical factor in valuing pink Argyle diamonds is color. The depth and purity of the pink hue significantly impact the diamond’s price. Diamonds with more intense and vivid pink colors are exceptionally rare and command higher prices. The Argyle grading system, which includes classifications such as Fancy Vivid, Fancy Intense, and Fancy Light, helps in identifying and valuing the color intensity of these diamonds.


While color is paramount, clarity also plays a significant role in the valuation of pink Argyle diamonds. Clarity refers to the presence of internal or external imperfections, known as inclusions and blemishes, respectively. Diamonds with fewer and less visible inclusions are considered more valuable. However, due to the intense color of pink Argyle diamonds, minor inclusions often have less impact on their overall beauty and value compared to white diamonds.


The cut of a diamond influences its brilliance and overall appearance. Pink Argyle diamonds are often cut to maximize their color and brilliance rather than their carat weight. A well-cut diamond will reflect light internally from one facet to another, enhancing its color and radiance. Popular cuts for pink Argyle diamonds include the round brilliant, oval, and cushion cuts, each designed to showcase the diamond’s unique attributes.

Carat Weight

Carat weight is a measure of a lab made diamonds. Larger pink Argyle diamonds are exceedingly rare and, therefore, more valuable. However, due to the scarcity of these diamonds, even smaller pink Argyle diamonds can be highly prized.

Investment Strategies for Pink Argyle Diamonds

Diversify Your Portfolio

As with any investment, diversification is essential. Including pink Argyle diamonds as part of a broader investment portfolio can mitigate risk and enhance potential returns. These diamonds can act as a hedge against market volatility, offering a tangible asset that retains value over time.

Focus on Quality Over Quantity

When investing in pink Argyle diamonds, prioritize quality over quantity. High-quality diamonds with exceptional color, clarity, and cut will appreciate more significantly over time than larger quantities of lower-quality stones. Investing in a single, high-quality pink Argyle diamond can often yield better returns than multiple lower-quality diamonds.

The diamond market is influenced by various factors, including global economic conditions, fashion trends, and the availability of supply. Staying informed about these trends can help investors make educated decisions about when to buy or sell pink Argyle diamonds. The closure of the Argyle mine, for instance, has increased the scarcity and value of these diamonds, making them a more attractive investment.

Diamond appraisers, gemologists, and investment advisors with experience in the gemstone market can provide insights and guidance, helping investors navigate the intricacies of pink Argyle diamond investments.

As the existing supply diminishes, the rarity and value of these diamonds are expected to increase. Investors who acquire pink Argyle diamonds now are likely to see substantial appreciation in value over the coming years.

Long-term Appreciation

Historically, pink Argyle diamonds have demonstrated strong long-term appreciation. The limited supply, combined with increasing demand from collectors and investors, ensures that these diamonds remain a sound investment. The unique characteristics and provenance of each pink Argyle diamond add to their desirability and value, making them a prized asset for discerning investors.

The global demand for pink Argyle diamonds continues to rise, driven by their rarity and beauty. Markets in Asia, particularly China and India, have shown a growing appetite for these gemstones, further bolstering their investment potential.
