It has been more than two decades since diamond ages have proven to be up to billions of years older than their host magmas of kimberlite or lamproite. Since then, there have been significant advances in the analysis of diamonds and their mineral inclusions, in the understanding of diamond-forming fluids in the mantle, and in the relationship of diamonds to the deep geology of the continents and the convecting mantle. The occurrence of natural diamonds is remarkable and important to earth studies. This article reviews current thinking of where, how, when, and why natural diamonds form.

Umm, diamonds are made of carbon. Therefore they must contribute to global climate change somehow. Therefore they must be banned. You may ship them all to me for proper disposal...
Seriously though, it was a pleasure to read this article reporting actual SCIENCE, not bullshiite propaganda.
