No one has ever visited the depths of our planet. However, a team of researchers from GIA and other institutions were able to gain incredible insight into the deep mantle \u2013 660 km below the surface \u2013 by examining a diamond that in fact did ride a volcanic eruption to the surface.<\/p>\n\n\n\n

Led by Dr. Tingting Gu, a GIA post-doctoral research fellow at the time of the research and now at Purdue University, the researchers, including GIA\u2019s Vice President of Research and Development Dr. Wuyi Wang, examined an exceptionally rare type IaB diamond from the Karowe mine in Botswana. The 1.5-carat, D-colour diamond\u2019s inclusions, examined using advanced, non-destructive methods including FTIR, Raman spectroscopy and X-ray diffraction, revealed that water can be found at least across the earth transition zone (410 \u2013 670 km deep) and into the lower mantle (more than 670 Km deep).<\/p>\n\n\n\n

When the diamond was submitted to GIA for evaluation \u2013 GIA sees millions of diamonds every year \u2013 researchers were intrigued by its unusual inclusions. These turned out to be very rare hydrous (water-bearing) minerals, suggesting the presence of water far deeper in the earth than previously believed.<\/p>\n\n\n\n

Speaking about the research, Dr. Wang said, \u201cMineral inclusions in diamonds are the only materials from the earth\u2019s interior that we can analyse directly. The study of these minerals offers unique opportunities to understand the chemistry of the Earth\u2019s interior. GIA has been actively contributing to this fundamental research.\u201d<\/p>\n\n\n\n

The Richard T. Liddicoat Postdoctoral Research Fellowship program, created in 2014 in honour of GIA\u2019s former president, who was widely considered the \u201cFather of Modern Gemmology,\u201d gives researchers who study mineralogy, geology, physics, materials science and other fields related to gemmology access to GIA\u2019s gemmological data, equipment and the rare, unusual and large gems that come into the laboratories.<\/p>\n\n\n\n

The paper was published in late September in the scientific journal Nature Geoscience<\/em> \u2013 you can see an abstract here<\/a>. Popular Science<\/em> magazine published an article<\/a> about the paper on 27th<\/sup> September.<\/p>\n\n\n\n

In addition to Gu and Wang, a large team from GIA contributed to the research, including research scientists and technicians, photomicrographers, executives and GIA board members.<\/p>\n","protected":false},"excerpt":{"rendered":"
