Here are some key facts about the Argyle Diamond Mine:

The Argyle Diamond Mine once proudly produced a staggering 90% of the world's pink diamonds, cementing its reputation as the primary source for these captivating gems.

During its remarkable 37-year run, the mine yielded over 865 million carats of rough diamonds. However, only a mere 5% of these diamonds possessed the coveted gem quality. Among this select few, approximately 80% are brown diamonds, 15% are yellow, 4% are colorless, and a mere 1% shines in enchanting shades of pink, red, blue, or violet - colors that are exceptionally rare.

Over the past four decades, Australian pink diamonds from the Argyle mine consistently commanded the highest prices among all pink diamonds, owing to their unparalleled beauty and scarcity.

Why Are Argyle Diamonds So Special?

Rare Argyle pink diamonds are renowned for their intense and vivid hues. The color spectrum of these gems stands unmatched when compared to loose pink diamonds from other origins. The profound richness of their shades renders the Argyle diamonds uniquely enchanting and highly sought after.

Many gemologists believe these diamonds' unique color qualities result from their formation within Lamproite, a volcanic rock known for its influence on diamond coloration. This unique environment plays a pivotal role in influencing the diamond's coloration. The presence of specific trace elements and conditions within Lamproite can lead to the development of the distinctive pink and purplish-pink hues seen in Argyle diamonds.

The grading system consists of four categories: purplish pink (PP), pink rose (PR), pink (P), and pink champagne (PC). 

Each stone is further assigned an intensity rating ranging from 1 (highest) to 9 (lowest). Additionally, all Argyle diamonds above 0.08 carat come with their own certificate, a comprehensive color grading report, and a laser inscription.

It's not uncommon to find Argyle pinks with certifications from the Argyle Diamond Mine and GIA.

are argyle pink diamonds increasing in value

The closure of the Argyle Mine, responsible for nearly 90% of the world’s pink diamond supply, has rocked the diamond industry. Notably, the first Argyle diamonds, recognized for their fancy vivid purplish pink shades, have become even more sought-after. In 2019, mining at Argyle showed a decline, producing only 80% of its usual pink diamonds. This dip in production has been described by Argyle experts as a significant contributor to the surge in value.

Today, the fancy vivid purplish pink and intense pink diamond varieties from the mine have seen price hikes of 20-30% annually. With each diamond certificate indicating the diamond's grade, it's evident that diamonds are graded with higher value when their hue leans towards the unique fancy purplish tones. The collection of Argyle diamonds, renowned for their distinct shades, will undoubtedly fetch even higher prices in the future. Unless a new source is found, the legacy of the first Argyle diamonds and the decreasing supply will cause prices to soar astronomically.

Can pink diamonds be made in a lab? 

Can pink diamonds be made in a lab? Yes, lab grown pink diamonds can be created. However, there's a significant difference in the value and perception between natural and lab-grown diamonds. Natural diamond, especially those with fancy vivid pink or fancy deep pink diamond hues, have seen their prices skyrocket. In contrast, pink lab diamonds, despite having a range of pink diamond shades from faint pink to more intense hues, are sinking in value. De Beers introduced their Lightbox brand, offering lab-grown diamonds at affordable prices, suggesting it's only a matter of time before all synthetic diamonds lose their worth. 

One might wonder: if natural and lab-grown stones have the same chemical composition, why such a price gap? It's akin to the disparity between natural Bulgarian rose oil and its synthetic counterpart, where the natural variant is valued 35x more. Just as a real, natural fancy red diamond recently sold for about $1 million, natural fancy pink diamonds maintain their allure and unmatched value. So, while lab-grown pink diamonds offer an alternative at a reduced price, they can't match the rarity and prestige of their natural counterparts. As the saying goes, "diamonds are forever," emphasizing the timeless appeal of natural stones.
