Canavesite, Mg2(HBO3)(CO3)∙5H2O, is a rare carboborate mineral from the abandoned Brosso mine in Italy. Canavesite is a secondary mineral that occurs due to the weathering of ludwigite-magnetite skarn on the surface of mine walls. The physical properties consist of milky-white rosette-like aggregates of elongated transparent fibers shown in figure one. It has the crystal symmetry of a monoclinic with a diffraction symbol of 2/mP-/-.
