Even diamonds can evaporate

Diamonds are the earth’s hardest naturally occurring substance. They are actually one of the forms of carbon, and were thought to be one of the most stable, never degrading substances. But a recent study of them revealed that the diamonds can even disappear when they are exposed to intense ultra violet rays.

Researchers, at Macquarie University, in their experiment and was reportedly published in ‘Optical Materials Express’ journal. According to them, the diamond can evaporate by UV light. The experiment was led by Prof. Richard Mildren. In the research, the diamonds were exposed to intense light pulses in UV-C band, and this resulted in small pits over the surface of diamond’s surface, only after a few second exposures. Various other findings were also concluded by these experimental results, as the rate of evaporation is very small and not noticeable under normal conditions. In fact, even under very bright UV conditions, such as intense sunlight or under UV tanning lamp, it would take approximately some 10 billion years, to see an observable change.

So, diamond will be with you till few other new facts come up.
