Hexagonal diamond up to 60 per cent stronger than normal diamonds could be used to create super-tough drilling and cutting ...

Right now, the diamonds are small—the largest is roughly 70 microns wide, or roughly the width of a human hair, according to Narayan. But he is confident the process can be scaled up.

The structure, an interlocking form of graphite and diamond, has unique properties that could one day be used to develop superfast charging or new types of electronics, researchers say. The ...

A new form of diamond has been created. Its unique structure gives it properties that are similar to those of natural diamonds, but it is more stable under extreme heat, so may be useful in tools ...

A typical Type IIa diamond will command a 5 to 15% premium and could be more in rarer large diamonds. Lucapa estimated that the 404-carat diamond could be worth upwards of $20 million.

DIAMOND is generally thought to be one of the most perfect crystals occurring naturally: its atomic structure was first investigated in the very early days of X-ray crystal analysis. It turned out ...
