Grandviewite from the Capillitas mine forms globular masses up to a couple of millimeters in diameter, formed by very thin platy to acicular lath-like crystals, greenish-pale blue in color, pleochroic (X = colorless, Y = very pale blue, Z = greenish-pale blue), with pale blue streak and silky to a satiny luster. Results of electron-microprobe study and crystal-structure determination lead to the new ideal formula Cu3Al2(SO4)(OH)10.H2O.
