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 ...

Structure diagrams of diamond and so-called lonsdaleite show their difference. Both consist of tetrahedrally coordinated carbon atoms (black balls) that form layers. For ordinary diamond, 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 ...

Rare diamonds found in meteorites called ureilites have a folded hexagonal structure. Learning the process of how they were formed could inspire better lab-grown diamonds.

The diamond structures were locked inside the Canyon Diablo meteorite, which slammed into Earth 50,000 years ago and was first discovered in Arizona in 1891. The diamonds in this meteorite aren't ...

Diamond is optically transparent to lightwaves of a wide range of wavelengths, including the visible spectrum between 400nm and 750nm. It is due to this fact that diamond is particularly useful in ...

The diamond structures were locked inside the Canyon Diablo meteorite, which slammed into Earth 50,000 years ago and was first discovered in Arizona in 1891. The diamonds in this meteorite aren't ...

WE have applied the new methods of investigation involving the use of X-rays to the case of the diamond, and have arrived at a result which seems of considerable interest. The structure is ...
