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 ...

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 ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...

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 ...

We’re used to volcanoes spewing up magma and ash, but sometimes they’ll gush forth diamonds. And sometimes, those diamonds carry with them strange forms of matter from the deepest bowels of the earth, ...

In this work, we demonstrate that ultraviolet (UV) laser photolysis of hydrocarbon species alters the flame chemistry such that it promotes the diamond growth rate and film quality. Optical emission ...

Paving the way to a dry process with less environmental impact Tools coated with diamond film (diamond-coated tools) are used for difficult-to-machine materials such as CFRP. In the manufacture of ...
