Tyrolite is a hydrous calcium copper arsenate carbonate mineral with the formula CaCu5(AsO4)2CO3(OH)4⋅6H2O.
Tyrolite forms glassy, blue to green orthorhombic radial crystals and botryoidal masses.
It has a Mohs hardness of 1.5–2.0 and a specific gravity of 3.1–3.2.
It is translucent with refractive indices of nα = 1.694, nβ = 1.726, and nγ = 1.730.
