Minéral (carbonate de magnésium) du système cristallin rhomboédrique, du groupe de la calcite, à clivages parfaits, à éclat vitreux, incolore, jaune ou brun.

CONT

La giobertite ou magnésite est assez rarement cristallisée, plus souvent en masses granulaires ou compactes, blanche à l'état pur, plus fréquemment teintée en brun par la présence de fer. Les giobertites sont [...] souvent un peu ferreuses [et ont] un éclat un peu nacré [...]. À l'état pur, c'est un minéral rare. Les beaux gisements de giobertite sont activement recherchés par l'industrie [...]
