Pink diamonds are among the rarest colored diamonds in the world, and with the largest producer of natural pink diamonds closing in November 2020, these diamonds are about to become much rarer (and potentially more valuable.)

With that in mind, let’s answer the most commonly asked questions about pink diamonds.


Why Are Pink Diamonds Pink?


Pink diamonds are pink due to deformities in their anatomical structure. Contrary to many other colored diamond categories, pure pink diamonds show no chemical impurities and are comprised entirely of carbon. When mentioning abnormalities in anatomical structure, gemologists are referring to lattice defects that have resulted from the stone being exposed to immense amounts of stress during its formation. These internal defects essentially cause the light that enters the prism to bend in ways that allows only shades of pink to escape (ranging from deep red to very light pink). 


Where Do Pink Diamonds Come 



Natural pink diamonds can come from mines all over the world, including India, Canada, Brazil, Russia, Siberia, and South Africa, but the Argyle Mine in Australia was the largest producer and distributer within the industry. The Argyle mine ceased operations in November 2020. So far, there haven’t been other mines that could come close to producing the volume and quality of diamonds the Argyle could, making high grade pink diamonds considerably rarer in the market.


Are Pink Diamonds Expensive?


Yes, pink diamonds are among the most expensive and rarest colored diamonds in the world. Their value has constantly been rising during the past decade and due to the closure of the Argyle Mine in late 2020 (making the diamonds considerably rarer,) their value is expected to continue to grow exponentially.

What Affects Pink Diamond Price?

Pink diamond prices are largely affected by the 4Cs: Color, Clarity, Carat Weight, and Cut. The higher the grade and quality of each C, the greater the price. There are however 2 more attributes that affect pink diamond prices; color modifiers and color undertones. Color modifiers represent the existence of additional hues that will either appreciate or depreciate the diamond’s value.  In the case of pink diamonds, the secondary hue is usually purple, orange, or brown. On the other hand, different undertones or “tints” based on geographic region with the most prominent ones being Australia and South Africa. Australia (typically the Argyle Mine’s bubble gum pink) offers beautifully saturated vivid pink stones while South Africa’s pink diamonds usually have nice bright and “cold” undertones.

Rarity is also a significant factor of pink diamond price. The closure of the Argyle mine means that supply of pink diamonds will be cut considerable, and certain types of pink diamonds will be finite and only available in the secondary market. This will potentially cause pink diamond values to rise in the coming years.

Are Pink Diamonds Worth the Investment?

Yes, pink diamonds are worth the investment, especially those that originate from the Argyle mine. With the closure of the mine, these diamonds are now finite. After the final Argyle Tender held in September 2021, all pink diamonds will only be available in the secondary market, and due to heightened demand and no supply, their value is expected to increase.


Which is the Most Expensive Pink Diamond in the World?
