A small planet and a big asteroid are thought to have crashed into each other 4.5 billion years ago, which is when the diamond was made.
In a recent study, scientists from Australia and the United Kingdom revealed how a strange diamond from a long-gone dwarf planet ended up on Earth’s surface.
According to CNN, geologist Andy Tomkins, an Australian professor who works in the field of classifying meteorites, began to make the revelation. Alan Salek, who helped write the study and is a researcher at RMIT University, says he found a strange “bent” type of diamond in a space rock in Northwest Africa.
Further research revealed that the meteorite included lonsdaleite, a rare hexagonal stone.
According to the study, Lonsdaleite is believed to have been created “from a supercritical fluid at a high temperature and moderate pressure.”
In a piece written by RMIT University, one of the research partners, Tomkins was cited as saying, “Later, lonsdaleite was partially replaced by a diamond as the atmosphere cooled and the pressure fell.”
It is thought that the dwarf planet and a big asteroid crashed into each other about 4.5 billion years ago, making the diamond.
The diamond’s strange hexagonal shape could make it stronger than most diamonds on Earth.
Lonsdaleite has been found to have a higher strength than conventional diamonds, which have a cubic structure. Academics believe that its strange creation may have important technical applications.
However, some of the strongest gems have also been found in meteorites, and they are fundamentally different from their terrestrial counterparts. Although it is common to think of diamonds as having formed under the intense pressures present deep inside the Earth, they have also been discovered in natural settings.
