Pink diamond

About Pink Diamond:

• Pink diamonds, also known as fancy pink diamonds, are some of the rarest and most coveted gemstones in the world.
• Pink diamonds have uniquely bent crystalline structures.
• More than 90% of all the pink diamonds ever found come from a single mine in the Kimberley region of Western Australia.
• All diamonds are found in pipelike volcanoes or in their eroded remnants. 
• How did they form?
  • Around 1.8 billion years ago, Western Australia and Northern Australia collided in a cataclysmic event.
  • This impact is believed to have been the catalyst that transformed once-colourless diamonds into their pink variants.
  • Scientists found that at Argyle, diamonds crystallised deep in Earth’s interior were brought to the surface when a supercontinent, Nuna, began to break apart.
  • As continents break up, their edges stretch, allowing small pockets of diamond-rich magma to rise to the surface.

What is Nuna?

• It is an ancient supercontinent that graced our planet’s surface.
• Scientists believe Nuna existed around 1.6 to 2.5 billion years ago, predating even the famous Pangea by a considerable margin.
• Researchers actively map Nuna’s formation by piecing together geological and paleomagnetic data.
• These clues suggest that Nuna brought together fragments of what we now identify as North America, northern Europe, and parts of Siberia.
• This supercontinent experienced multiple cycles of coming together and breaking apart. Each phase of assembly and dispersal reshaped the Earth’s surface.
• These changes gave rise to new geological formations, laying the groundwork for subsequent continents.
• One of the most intriguing findings about Nuna lies in its connection to Earth’s atmospheric evolution.
• As Nuna formed, volcanic activities increased. These volcanoes released vast amounts of carbon dioxide, playing a pivotal role in shaping the planet’s early atmospheric conditions and potentially influencing the course of life.
