Oval engagement rings are a classic choice for a reason. We break down everything to know about the popular cut from its history to unique setting choices for the stone.

With the right amount of pressure and surprisingly little heat, a substance found in fossil fuels can transform into pure diamond. It sounds like alchemy: take a clump of white dust, squeeze it in a ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

Researchers named it lonsdaleite, after crystallographer Kathleen Lonsdale, but for decades, no one was sure it truly existed. For 60 years, the material had only been reported in meteorite impact ...

Like many of you, we’ve been watching the horrifying developments in the Middle East. As the war with Iran causes violence to spread around the region, nobody knows how long this conflict will last.

Tiny diamond particles can help fabric release heat—and despite being diamonds, they're surprisingly affordable to make.

Scientists create first-of-its-kind ‘hexagonal diamond’ harder than real thing - Material exhibits slightly higher hardness than naturally found diamond ...

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Ski mountaineering, or “skimo,” will make its Olympic debut this week. The idea is simple: race uphill fast, then ski back down fast.

“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.
