Diamonds Not As Rare As People Might Think, Say Scientists

The findings “constitute a new quantitative theory” about how diamonds are formed, according to researchers at the Johns Hopkins University in the United States. “Diamond formation in the deep Earth—the very deep Earth—may be a more common process than we thought,” says Johns Hopkins University geochemist Dimitri A. Sverjensky.

However, diamonds are not going to become cheaper for consumers as a result. Firstly, the prevalence of diamonds near the Earth’s surface where they can be mined still depends on relatively rare volcanic magma eruptions that raise them from the depths of the Earth where they are created. And secondly, the diamonds considered in Sverjensky’s studies are tiny, with most of the gems being only a few microns across and not visible to the unaided eye.
