Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting graphite to extreme pressure and heat, researchers synthesized a rare ...

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 ...

The natural diamonds that were hoarded by potentates ... most diamonds appear roughly rounded with perhaps a hint of regular crystal form. Many are colorless, but most are pale shades of yellow ...

This synthetic creation possesses a hexagonal crystal form, which provides much greater strength compared to the cubic structure of most natural diamonds. The "super diamond" structure exhibits ...

Physicists at Washington University have forged ahead in the field of quantum mechanics by creating a new phase of matter ...

Natural red diamonds are among the rarest gemstones ... get their pigmented appearance from atomic impurities in their crystal structure, the Winston Red Diamond’s crimson hue “is the product ...

In the literature 5, the indentation hardness of single crystals of natural diamond has been reported to be 143 ± 6 GPa (Berkovich diamond indenter under a load of 2 N). Therefore, it is ...

Lab-grown diamonds outpace natural stones when it comes to engagement rings. Here’s why, and what to consider when shopping.

Natural diamonds mostly have a cubic lattice – or arrangement of their carbon atoms – but a hexagonal crystal structure is known to provide a much stronger material. However, researchers say ...

In general, lab-grown diamonds can sell for around one-tenth the price of a comparable natural diamond, according to Paul Zimnisky, a global diamond industry analyst and founder of Paul Zimnisky ...
