Une enqu\u00eate passionnante dans le monde du diamant, des mines d’extraction aux plus belles pi\u00e8ces de joaillerie. <\/p>\n

Le diamant est la plus dure des substances naturelles connues et l’une des plus anciennes g\u00e9ologiquement parlant. Form\u00e9s de cristaux de carbone presque compl\u00e8tement purs \u00e0 plus de 150 kilom\u00e8tres sous la surface de la Terre, certains peuvent dater de trois milliards d’ann\u00e9es !
\nD\u00e8s l’Antiquit\u00e9, cette pierre \u00e0 l’\u00e9clat incomparable fut d\u00e9crite comme le symbole du luxe et de l’opulence. Jusqu’\u00e0 la fin du XIXe si\u00e8cle, on ne connaissait que deux sources d’approvisionnement : l’Inde puis le Br\u00e9sil. \u00c0 la fin du XVe si\u00e8cle, alors que les navigateurs portugais inauguraient les routes maritimes vers ces pays, les Juifs install\u00e9s \u00e0 Lisbonne s’\u00e9taient lanc\u00e9s dans la taille et le n\u00e9goce du diamant. Pour \u00e9chapper aux pers\u00e9cutions, nombre d’entre eux s’\u00e9tablissent \u00e0 Amsterdam, Anvers et \u00e0 Londres. Mais le commerce de la pierre ne se d\u00e9veloppe v\u00e9ritablement qu’\u00e0 la fin du XIXe si\u00e8cle au moment o\u00f9 la soci\u00e9t\u00e9 De Beers lance une exploitation syst\u00e9matique en Afrique du Sud puis sur tout le continent africain (Congo, Angola, Namibie, Sierra Leone, Botswana). Un changement historique est intervenu ces dix derni\u00e8res ann\u00e9es avec le processus de Kimberley – les Nations unies interviennent pour mettre un terme \u00e0 des guerres financ\u00e9es par le diamant et parrainent un contr\u00f4le international sur les exportations de diamants bruts.<\/p>\n","protected":false},"excerpt":{"rendered":"
