Scientists stated they have found the ‘missing ingredient’ for pink diamonds – some of the world’s most expensive stones due their rarity and beauty. Notably, more than 90% of all the pink diamonds ever found were discovered at the recently closed Argyle mine in the remote north-west of Australia. A team of Australia-based researchers said the pink diamonds were brought to the Earth’s surface by the breakup of the first supercontinent around 1.3 billion years ago. The first ingredient is carbon and the second ingredient is just the right amount of pressure to damage the otherwise clear diamon.
