They don’t make them like they used to — at all. It can take natural diamonds over three billion years to grow, but researchers in a South Korean lab have successfully fabricated the precious stones ...

The Okavango Blue Diamond, a dazzling 20.46-carat stone, is more than just a beautiful jewel-it's practically a miracle of nature. Unearthed from the Orapa mine in Botswana, this rare gem has ...

A groundbreaking technique developed by scientists now allows for the synthesis of diamonds at normal atmospheric pressure and without the need for a starter gem — in just 15 minutes. Traditionally, ...

A pair of diamonds that formed hundreds of kilometers deep in Earth's malleable mantle both contain specks of materials that form in completely opposing chemical environments — a combination so ...

The discovery of two diamonds originating from the depths of the Earth's mantle reveals a chemical coexistence that scientists had until now deemed unimaginable. These precious stones, formed several ...

Jeweler Harry Winston donated the famous Hope Diamond—the largest-known deep blue diamond in the world—to the Smithsonian Institution in 1958. It arrived in a plain brown package by registered mail, ...

A simulated form of carbon called BC8, or 'super-diamond', could be 30% tougher than normal diamonds, but synthesizing it on Earth won't be easy. When you purchase through links on our site, we may ...

In a new study published in Nature Physics, researchers achieved the first experimental observation of a time rondeau crystal—a novel phase of matter where long-range temporal order coexists with ...
