SCIENTISTS EXPLAINED THE ORIGIN OF DIAMONDS

Posted: 14/12/2017

Diamonds may not be as rare as once believed, but this finding in a new Johns Hopkins University research report won't mean deep discounts at local jewelry stores.

"Diamond formation in the deep Earth, the very deep Earth, may be a more common process than we thought," said Johns Hopkins geochemist Dimitri A. Sverjensky, whose article co-written with doctoral student Fang Huang was published Tuesday in the online journal Nature Communications. The report says the results "constitute a new quantitative theory of diamond formation," but that does not mean it will be easier to find gem-quality diamonds and bring them to market.

For one thing, 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 where they form. For another, the diamonds being considered in these studies are not necessarily the stuff of engagement rings, unless the recipient is equipped with a microscope. Most are only a few microns across and are not visible to the unaided eye.
