What is Pink Diamond?
A pink diamond is a type of diamond that displays a natural pink colour due to unique structural and chemical characteristics. Unlike other gemstones, pink diamonds are purely carbon crystals, like other diamonds, but their pink hue is caused by distortions in their crystal lattice, rather than the presence of trace elements.
Pink diamonds are highly prized for their rarity, vibrant colour, and exceptional brilliance. Even small stones can command remarkable attention and value in the jewellery market.
Key points:
-
Pink diamonds are naturally occurring carbon crystals with a pink hue.
-
Colour arises from structural lattice distortions rather than chemical impurities.
-
Highly rare and valued for their vivid colour and brilliance.
-
Each pink diamond is unique in hue, intensity, and sparkle.
-
Used primarily in fine jewellery and high-value collections.
-
Their rarity makes them highly desirable for investors and collectors.
How Does Pink Diamond Form?
Pink diamonds form deep within the Earth under extreme heat and pressure, just like other diamonds. What sets them apart is the deformation in their crystal lattice during formation, which causes light to scatter in a way that produces the pink colour.
Some scientists suggest that the lattice distortion is caused by immense geological forces, such as tectonic movement or shock events, millions of years ago. The formation process is incredibly slow, allowing the diamond to develop its unique colour and exceptional clarity over billions of years.
Key points:
-
Forms deep in the Earth under high heat and pressure like other diamonds.
-
Pink colour arises from lattice distortions rather than trace elements.
-
Geological forces or shock events contribute to lattice deformation.
-
Formation takes millions to billions of years, producing rare, high-quality crystals.
-
Colour intensity depends on the degree of lattice distortion.
-
Each pink diamond is geologically unique, making every stone different.
Where is Pink Diamond Found?
The majority of the world’s pink diamonds come from the Argyle mine in Western Australia, historically the most prolific source. Other occurrences are extremely rare, including mines in Brazil, South Africa, and India.
Because pink diamonds are so scarce, every new discovery is highly significant. Argyle pink diamonds, in particular, were renowned for their intense colour, though the mine ceased operations in recent years, further increasing rarity and value.
Key points:
-
Primarily sourced from the Argyle mine in Western Australia.
-
Other rare sources include Brazil, South Africa, and India.
-
Extremely limited supply makes them highly sought after.
-
Closure of the Argyle mine has increased rarity and investment potential.
-
Colour intensity varies depending on geographic origin.
-
Mines producing pink diamonds are incredibly scarce worldwide.
Properties of Pink Diamond
Pink diamonds share the hardness of all diamonds, scoring 10 on the Mohs scale, making them extremely durable. They exhibit exceptional brilliance and fire due to diamond’s refractive properties, with light reflecting and dispersing in a way that creates a vibrant sparkle.
Their colour is graded based on hue, tone, and saturation. Stones can range from faint pink to intense, vivid pink. The combination of hardness, sparkle, and colour makes pink diamonds highly desirable for collectors and jewellers alike.
Key points:
-
Hardness of 10 on the Mohs scale; extremely durable.
-
Brilliance and fire enhanced by diamond’s refractive properties.
-
Colour graded by hue, tone, and saturation from faint to vivid.
-
High value results from rarity, colour intensity, and clarity.
-
Exceptional hardness allows use in everyday jewellery.
-
Visual appeal combines sparkle with rare pink colouration.
