Diamonds are pure carbon and natural antiques (2.8 &#8211; 3.2 billion years) that form at depths greater than 200 km in selectively old, cold and stable continental cratons. Brought to the surface volcanically in explosive kimberlite pipes, these&nbsp;preciously&nbsp;sought after&nbsp;gems hold an enormously rich information repository on: the early primordial Earth, sources of carbon, processes of fractionation, magmatic evolutionary events; and with plume-generated volcanism triggered at the core-mantle boundary (2,900 km depth), diamonds, the host rocks to diamonds, and mineral inclusions in diamonds, provide an unprecedented sample of Earth&#8217;s deep interior. His current studies are wide-ranging from field activities in Brazil, India, South Africa, and West Africa (fingerprinting&nbsp;&#8220;Blood Diamonds&#8221;), to the cosmos, pre-solar diamonds (greater than 4.5 billion years old), and the enigmatic origin of black and porous carbonado-diamond.
