Diamond-bearing kimberlites are volcanic rocks that originate deep in the Earth and are erupted onto the surface. Researchers have now shown that other rock types, incorporated into the magma as it ...

A vulcanologist at the University of British Columbia may have cracked the riddle on how kimberlite magma, and the valuable diamonds it sometimes carries, pushes its way up from deep underground.

kimberlite, a type of igneous rock, and new research has revealed how diamonds are transported without being carbonized when they rapidly rise from deep within the Earth and erupt to the surface. Why ...

Scientists have long known that a diamond's trip from deep below Earth's surface must be quick indeed: Lab tests show that at conditions found in the crust, the gems would burn up in a matter of days, ...

Drawing from geology and volcanology, scientists propose an integrated and dramatic mechanism for the formation of kimberlites, the enigmatic structures bearing most of the world's diamonds. Their ...

"A diamond is forever." That iconic slogan, coined for a highly successful advertising campaign in the 1940s, sold the gemstones as a symbol of eternal commitment and unity. But our new research, ...

Scientists have found the main driving force behind the generation and eruption of diamond-rich magma, which can also help find more. Israel’s Ramat Gan is still the leading center for cutting big ...

A funnel of hard, green-tinged rock spears into the Earth’s crust, rising up out of the mantle 250km below. This rock contains diamonds and the secrets of how to find them. Deep inside the mantle, ...
