A new process of diamond formation has been theorized that could indicate they are more plentiful than thought. It involves the acidification of water at great depths, producing minuscule diamonds in ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

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. For one thing, the prevalence of ...

How old do you think the average diamond is? One thousand years? One million, maybe? Try one to three billion years old. Diamond formation is not a fast or simple process. In addition to time, it also ...

Geologists have studied tiny pockets of fluids trapped inside diamonds to get a better understanding of how old humanity’s favorite rocks might be. In doing so, they identified three distinct periods ...

Boundaries between tectonic plates may make ideal diamond nurseries, according to an experiment that mimics conditions deep in the Earth. Diamonds form only at temperatures and pressures far greater ...

Hydrocarbon mixtures are extremely abundant in the Universe, and diamond formation from them can play a crucial role in shaping the interior structure and evolution of planets. With first-principles ...
