Nitrogen is ubiquitous in both natural and laboratory-grown diamond, but the number and
nature of the nitrogen-containing defects can have a profound effect on the diamond …

Most diamonds are metasomatic minerals, which means they grew from fluids or melts that
moved through solid mantle rocks and chemically interacted with them. The involvement of …

Defect-free diamond is an important physics playground and technological tool due to its
well-known list of superlative properties, such as its hardness, thermal conductivity …

The origin of cratonic diamonds is reviewed on the basis of nearly 5000 analyses of silicate,
oxide and sulphide inclusions in diamonds. Compositional fields are defined for common …

Diamondiferous rocks from the Kokchetav Massif, Kazakhstan, represent deeply subducted
continental crust. In order to constrain the age of ultra high pressure (UHP) metamorphism …

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 …

The infiltration of fluids into continental lithospheric mantle is a key mechanism for
controlling abrupt changes in the chemical and physical properties of the lithospheric root …

Since first being discovered in India over 2000 years ago, the most striking and universally
recognized shape of an uncut diamond is the octahedron. This shape was revered from …

Alluvial diamonds from the Juina area in Mato Grosso, Brazil, have been characterized in
terms of their morphology, syngenetic mineral inclusions, carbon isotopes and nitrogen …

Diamonds have been shown to be an excellent platform for quantum computing and
quantum sensing applications. These applications are enabled by the presence of defects in …
