I introduce myself, my name is Remi Bornet, I'm 35 years old and I am a geologist and a GIA gemmologist. For nearly twenty years, I'm passionate about everything that comes from the Earth, collecting minerals and fossils. Since childhood I am attracted by what we have under our feet : The Earth. This thing so palpable and yet so difficult to understand, so powerful and uncontrollable... Today I finished my studies in geology at the University of Clermont-Ferrand in 2010 after defending my Master 2 on the pseudotachylites fusion mechanisms in the Ivrea Zone and the Dora Maira Massif. I also worked in 2009 on the lussatite, a variety of opal-CT that I particularly like. The Auvergne: the region where fire and water have communed together over millions of years, to give us today the landscape shapes the most voluptuous and most flamboyant colors, undoubtedly a crystalline reflection of its mineral resources. This consuming passion is probably what has taught me... In early 2009, I finally chose my path, lined with crystals, I created "Le Comptoir Géologique" (www.le-comptoir-geologique.com), a minerals and fossils commercial website, and currently writing articles and improve my knowledge mineral matter : my passion.
