Roméite is a calcium antimonate mineral with the chemical formula (Ca,Fe,Mn,Na)2(Sb,Ti)2O6(O,OH,F). It is a honey-yellow mineral crystallizing in the hexoctahedral crystal system. It has a Mohs hardness of 5.5-6.0. It occurs in Algeria, Australia, Brazil, China, Europe, Japan, New Zealand, and the United States in metamorphic iron- manganese deposits and in hydrothermal antimony-bearing veins.
Its type locality is Prabornaz Mine, Saint-Marcel, Aosta Valley, Italy. It was named after Jean-Baptiste L. Romé de l'Isle. Brugger, et al. (1997) used infrared spectroscopy to measure water content in Roméite crystals.
