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 ...

Each week, The Daily’s Science & Tech section produces a roundup of the most exciting and influential research happening on campus or otherwise related to Stanford. Here’s our digest for the week of ...

It has been long believed that the basis of which diamonds form is coal. However, geologists have been disputing just how much of a role coal plays in the formation of these complex gemstones. So far ...

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 ...

There was a bit of shock recently when U.S. men's national team coach Jurgen Klinsmann opted for a 4-4-2 "diamond" instead of the 4-2-3-1 that had seen the Americans through qualifying. The new ...

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 ...

Carbon, oxygen, and nitrogen are some of the easiest heavier elements to form through fusion. As a result, they’re common in our Solar System, typically found combined with hydrogen to make ammonia, ...

Almost 100 million years ago, in what is now Pike County, nature created one of the world's most unusual diamond-bearing formations, the big volcanic "pipe" that now serves as the centerpiece of ...
