Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

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 that ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic diamonds.

After decades of chasing after a rare hexagonal diamond, a Chinese team says their iteration of the elusive material is the ...

Processing diamond surfaces with femtosecond lasers yields a trade-off between hydrophilicity and low defect rate.

Even with the weight of worlds on its shoulders, diamond resolutely refuses to buckle under the pressure. Thanks to the highest-pressure X-ray diffraction experiments ever reported, researchers have ...

Diamond stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report January ...
