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.

Archean cratons in South Africa have yielded gem diamonds such as these specimens from the GIA Museum’s Oppenheimer Student Collection. 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.

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.

The project objectives first consists in exploring and separating OSL emissions from quartz of different sensitivity to light and to isolate components suited for specific dating applications with the Linear Modulation technique.

Rapid environmental change with or without human impact will be dated more precisely and more reliably using this sophisticated technique.
