The world of diamonds is a sparkling realm of mystique, allure, and luxurious splendour. And yet, among all the dazzling gems available, pink diamond rings have long stood above the rest as the most sought-after and coveted. With their unique, vibrant hues and appreciating value, these exceptionally rare and magnificent gemstones have captivated the hearts of collectors, celebrities, and royalty alike for decades.

But what makes these stunning diamonds so highly prized?

In this article, our specialists at Pink Kimberley Diamonds delve deep into the world of the rare Argyle pink diamonds to unveil their unique charm and explore the factors that contribute to their unparalleled desirability.

The formation of Argyle pink diamonds is a geological marvel that dates back over 1.6 billion years. These diamonds are formed deep within the Earth's mantle, under extreme pressure and heat. The distinctive pink hue is attributed to the trace elements and distortions in the crystal lattice structure, which cause light to be absorbed and emitted as pink or red wavelengths.

The Argyle pink diamond mine, located in the remote East Kimberley region of Western Australia, is the primary source of these precious stones. Discovered in the early 1980s, this mine has been the primary source of these exquisite gemstones, producing over 90% of the world's pink diamonds.

After extraction, the rough pink diamonds undergo a meticulous sorting and grading process to assess their colour, clarity, carat weight, and shape. The highest quality stones are then cut and polished by expert craftsmen, transforming them into the stunning Argyle pink diamonds we see in luxurious jewellery pieces, such as a rare pink diamond ring, pendant, or even a broach.

One of the most significant reasons behind the high demand for rings set with Argyle pink diamonds is their rarity. Since the Argyle mine's closure in November 2020, the demand has further intensified alongside the scarcity of these gems, making them even more precious among collectors and investors.

Pink diamonds, in general, are extremely rare, too, with only one out of every 10,000 diamonds possessing this exquisite hue.

Another factor contributing to the high demand for these stunning rings are the diverse and intense colour palette these gemstones display. In fact, Pink diamonds from the Argyle mine are famous for the diverse scale of unique hues, from delicate pastel shades to deep, rich pinks and even rare purplish-pink tones. As mentioned above, these colours result from the presence of trace elements and extreme pressure during the diamond's formation, creating their distinctive and enchanting appearance.

The Argyle mine classifies its pink diamonds using a specific grading system based on their colour intensity and saturation. The system will place each gem within four separate categories:

-        Purple-pink (PP)

-        Pink (P)

-        Pink-rose (PR)

-        Pink-champagne (PC)

Each category will also have classifications based on the colour’s strength. For example, P1 is the most intense within the pink category and will range to P9 as the lightest, with the most coveted pink diamonds falling within the P1 to P3 categories. The rarity and intensity of these colours make pink diamond rings and jewellery pieces extraordinary and highly prized possessions.

Argyle pink diamonds are not just a symbol of luxury and exclusivity; they also hold exceptional investment value as an inclusion in your portfolio. Reasons to consider investing include:

• Portfolio Diversity: Pink diamonds offer a unique opportunity for portfolio diversification and long-term financial security, especially during times of market instability.
• Auction Performance: Pink diamonds have consistently outperformed other commodities at auction, reflecting their high demand and good liquidity.
• Stable Appreciation: With an average appreciation rate of 13.8%, pink diamonds have demonstrated consistent growth, even during economic crises, making them a smart long-term investment over other options, including the stock market and property.
• Market Volatility Insulation: Pink diamonds have maintained their growth trajectory despite market fluctuations, providing a level of insulation against market volatility and inflation.

What’s more, after the closure of the Argyle Pink Diamond Mine, the increasing scarcity of these precious stones, coupled with their inherent beauty and desirability, continues to create a surge in demand and, subsequently, a rise in their prices.
