From Argyle to Bubblegum A Guide to the Different Tones of Pink Diamond

For decades, Argyle pink diamonds were among the most sought-after gems in the world. Mined exclusively from the Argyle Mine in Western Australia, these diamonds displayed an unmatched intensity of pink hues, ranging from delicate blush tones to deep, rich magentas. The mine’s closure in 2020 marked the end of an era, making these diamonds even rarer and significantly increasing their value in the luxury jewellery market. Since the closure, demand has surged, with auction prices for Argyle pink diamonds reaching record highs. Their scarcity has led to limited availability, making them a prized possession for collectors and investors seeking a tangible asset with lasting value.

The rarity of Argyle pink diamonds stems from their unique geological formation. Unlike other diamonds, which derive their colour from chemical elements such as nitrogen or boron, natural pink diamonds owe their colour to structural distortions in their crystal lattice. These distortions, created under immense heat and pressure, scatter light differently, producing their distinctive pink shades. As a result, no two pink diamonds are ever exactly alike, enhancing their exclusivity.

Collectors and investors alike have turned to Argyle pink diamonds for their historical and financial significance. Due to their limited supply, they continue to be a top choice for investment, ensuring their status as some of the most valuable gems ever unearthed.

Fun Fact: Argyle pink diamonds account for less than 0.01% of the world’s diamond production, making them one of the rarest types of diamonds ever discovered.

What Causes the Beautiful Shades in Pink Diamonds?

The colour variations in pink diamonds have fascinated gemologists and collectors for years. Unlike yellow or blue diamonds, which owe their hues to specific elements, pink diamonds develop their shades due to intense pressure during their formation. This process alters the diamond’s atomic structure, affecting how light interacts with the stone and creating its distinctive pink tint.

Fancy pink diamonds shades range from soft pastel pinks to deep purplish hues. The Gemological Institute of America (GIA) classifies these diamonds based on intensity levels, from faint pink to fancy vivid pink. The more saturated the colour, the rarer and more valuable the diamond.

Factors influencing a pink diamond’s colour include:

1. The presence of secondary hues such as purple, brown, or orange.
2. The diamond’s size and cut, which affect how light enhances the colour.
3. The region where it was mined, with Argyle pink diamonds exhibiting the deepest shades.
4. The orientation of the diamond’s internal structure, which determines how colour is distributed across the stone.

The Spectrum of Fancy Pink Diamonds and Their Global Origins

While Argyle pink diamonds remain the most famous, pink diamonds are also mined in South Africa, Canada, Brazil, and Russia. These locations produce fancy pink diamonds in a variety of shades, though they rarely match the intensity of Argyle stones.

1. South African Pink Diamonds – Typically lighter and sometimes featuring a purplish tint.
2. Canadian Pink Diamonds – Often paler, with a soft glow that enhances their elegance.
3. Brazilian Pink Diamonds – Known for their earthy undertones, occasionally displaying a brownish-pink hue.
4. Russian Pink Diamonds – Rare and unpredictable in colour, ranging from faint pinks to deep, rich shades.

Pink diamonds from these locations provide collectors with a wide selection of tones, allowing for more variety in fine jewellery pieces. However, it is important to note that pink diamonds from different regions often have unique pricing and grading standards. For example, Argyle pink diamonds are graded using the Argyle colour classification system, which is separate from the standard GIA grading scale. This system ranges from 1PP (the most intense purple-pink) to 9P (the lightest pink shade), whereas non-Argyle pink diamonds are graded using GIA’s fancy colour categories. Additionally, Argyle pink diamonds generally command higher prices due to their strong market demand and historical significance, whereas pink diamonds from other locations may be more affordable depending on their hue and saturation. However, Argyle pink diamonds rarity ensures they remain the most valuable and desirable option.

The Rarity and Value of Purple-Pink Diamonds and Why They Are So Desirable

Among the rarest of pink diamonds are purple-pink diamonds, which feature a striking blend of pink with a violet or lavender undertone. These diamonds are highly sought after due to their uniqueness and scarcity, often fetching record prices at auctions.

Famous figures who have worn purple-pink diamonds include:

1. Jennifer Lopez, who was once gifted a stunning pink diamond engagement ring.
2. Blake Lively, known for her elegant pink diamond jewellery collection.
3. Victoria Beckham, who has owned multiple pink diamonds over the years.
4. Mariah Carey, who received a 17-carat pink diamond engagement ring, one of the most famous in history.

The purple-pink diamonds value is often higher than standard pinks due to their dual-colour intensity, making them a coveted choice among collectors. Their unique shade allows them to stand out in a world where pink diamonds are already incredibly rare.

Brownish-Pink Diamonds A Warm and Earthy Take on the Classic Pink

Brownish-pink diamonds offer a sophisticated alternative to traditional pinks. These stones blend earthy undertones with soft pink hues, resulting in a warm and elegant appearance.

Brownish-pink diamonds are becoming increasingly popular among jewellery designers who appreciate their subtle vintage charm. Their natural appeal makes them ideal for antique-inspired rings and bespoke jewellery pieces. Many collectors find them appealing due to their soft, romantic glow, which works well with both modern and vintage settings.

While not as intensely coloured as Argyle pink diamonds, brownish-pink diamonds luxury appeal lies in their affordability and uniqueness. They are often cut in vintage styles, such as cushion and oval shapes, to enhance their natural charm. Due to their rarity and growing appreciation, they are also becoming more valuable in the fine jewellery market.

Bubblegum Pink Diamonds The Boldest and Brightest Shade of Fancy Pinks

For those who love bold and vibrant colours, bubblegum pink diamonds provide an eye-catching option. These diamonds showcase a bright, playful shade of pink, often resembling the colour of candy.

The demand for bubblegum pink diamonds jewellery has risen in recent years, particularly among younger collectors who appreciate their youthful and lively appearance. Their electrifying hue makes them stand out, making them a perfect choice for those seeking a statement piece.

How to Choose the Perfect Pink Diamond Based on Colour and Investment Potential

Selecting the right pink diamond depends on personal taste, budget, and investment potential. Here are a few key considerations:

1. Colour Intensity – The richer the pink, the higher the value. Fancy vivid pinks hold the greatest investment potential.
2. Origin – Argyle pink diamonds are the most sought-after, but pink diamonds from South Africa, Canada, and Brazil provide unique variations.
3. Size and Cut – Larger stones with superior cuts enhance the diamond’s brilliance and colour.
4. Certification – Ensure your diamond is GIA-certified to verify authenticity and quality.
5. Secondary Tones – Purple-pink and brownish-pink diamonds provide rare and elegant alternatives.
6. Market Trends – Research current market trends to determine which shades are most in demand.
7. Long-Term Value – Choose diamonds that are expected to appreciate, particularly those from the now-closed Argyle Mine.

The closure of the Argyle Mine has further tightened supply, making high-quality pink diamonds an even more lucrative investment. In recent years, collectors have shifted focus to fancy vivid pinks, as their rarity ensures continued appreciation. Buyers should also monitor market trends and global auctions, as shifts in demand can influence future value. With the closure of the Argyle Mine, these diamonds are expected to appreciate even further in value.
