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 ...
The stable form of carbon at room temperature is Graphite which has a hexagonal crystal structure. (Top diagram) Diamond is metastable at room temperature and has a diamond cubic crystal structure.
Most diamonds found in nature and often used in jewelry display a cubic crystal structure, a repeating pattern of 8 atoms forming a cube with carbon atoms at its vertices.
The crystal has a lattice parameter of 0.541 nm. The crystal structure is also known as diamond cubic and may be thought of as two interpenetrating fcc lattices, one for sulphur the other for zinc, ...
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 has long been regarded as the practical and theoretical hardness champion and has found uses ranging from industrial abrasives to a girl's best friend. Cubic boron nitride, a synthetic ...
Chinese scientists have come up with a way to create a high-quality “super diamond” in the laboratory with a hardness far exceeding natural diamonds. The researchers behind the development say ...
