Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

One of the key scientific questions about diamonds is “how are they formed?” To answer this
question, we need to know the diamond-forming reactions and the physicochemical …

Diamond crystallization ages are essential information for science and industry, leading to
an understanding of how, why, and where diamonds form in Earth and how best to find …

The mineralogy and chemical compositions of inclusions in diamonds are the primary
source of information about the environment in which diamonds grow and help constrain the …

The thermobarometric analysis of inclusions in lithospheric diamonds has shown that these
diamonds may originate from a wide range of depths, with a global mode at~ 175±15 km …

Abstract Ferropericlase [(Mg, Fe) O] is one of the major constituents of Earth's lower mantle
and the most abundant mineral inclusion in sub-lithospheric diamonds. Although a lower …

Diamonds are unrivalled in their ability to record the mantle carbon cycle and mantle fO 2
over a vast portion of Earth's history. Diamonds' inertness and antiquity means their carbon …

Replicating lithospheric diamonds experimentally helps reveal their histories at depth, which
may be complicated by successive growth and dissolution episodes. Here, we present …

The origin and evolution of metal melts in the Earth's mantle and their role in the formation of
diamond are the subject of active discussion. It is widely accepted that portions of metal …

Study of inclusions in gems from secondary deposits can give valuable clues on the
geologic (and sometimes geographic) origin of these displaced materials. For the present …
