One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

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 …

Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

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 …

Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
