A star eventually explodes to release a cloud of galactic dust containing precious metals such as silver. This phenomenon is called Supernova. The particles released through supernova combined together to form various celestial bodies such as the planets of our solar system.
Diamonds are also formed similarly billions of years ago. They were hidden deep inside the Earth’s mantle and have slowly moved closer to the surface along with molten volcanic rocks. The golden diamond featured in this coin is 1.6 billion years old and has been excavated from the Argyle Diamond Mine in Kimberley.
