As part of their discovery, they found evidence that pink diamonds from the Argyle diamond deposit mine in Western Australia may date back to the time an ancient supercontinent, known as Nuna ...

The research team found that the Argyle deposits were 1.3 billion years old, from a time when an ancient supercontinent, known as Nuna, was breaking up into fragments.

The diamond-bearing rocks of the Argyle mine in Western Australia probably formed about 1.3 billion years ago, the analysis shows, along a rift zone that sundered the supercontinent Nuna.

Another, Rodinia, is thought to have existed between 1.3 billion and 750 million years ago. And there’s a third, Nuna (or Columbia), stretching back further than 1.4 billion years.
