Kimberlite

Researchers suggest that the famed Golconda diamonds, including the Hope Diamond and Koh-i-noor, may have originated from a volcanic outcrop nearly 200 miles from where they were mined.

Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil.

Here's everything you need to know about diamonds synthesized in the lab, and how they may (or may not) differ from their natural counterparts.

Most diamonds are formed deep inside Earth and brought close to the surface in small yet powerful volcanic eruptions of a kind of rock called "kimberlite".

Rocks are not nouns but verbs, says Marcia Bjornerud in her new book.

Their start dates back 300M years to the time of Pangaea, researchers say

A hotspot that now lies in the middle of the Atlantic Ocean was once under the Great Lakes, and may explain why they formed where they did.

A new study offers clues to the mysteries of kimberlite eruptions, the source of most of the diamonds mined on Earth today.

It was the world's largest diamond when mined and today it's cut into nine gems that are all part of the British Crown Jewels. But since the death of Queen Elizabeth II, questions have emerged about its imperialist history.

JOHANNESBURG — A big pink diamond of 170 carats has been discovered in Angola and is claimed to be the largest such gemstone found in 300 years. Called the "Lulo Rose," the diamond was found at the Lulo alluvial diamond mine, the mine's owner, the Lucapa Diamond Company, announced Wednesday

A crypto entrepreneur stated he won the auction for a 555.55 carat "space diamond" by paying over $4.2 million in crypto. Learn more.

Diamonds erupt from the deep as supercontinents break up. Now you can listen to the "song" of these kimberlite eruptions.

To get your hands on them, you just need to dig 160 kilometers beneath your feet.

An auction house claims that the carbonado came from interstellar space, but a geologist we spoke to isn't so sure.

The rarity of precious gemstones comes down to the geologic process of their formation.

Diamonds seem to reach Earth's surface in massive volcanic eruptions when supercontinents break up, and they form when continents come together.
