Only as mineral specimens Specimens Cuproadamite is not always thought of as a separate mineral from its close cousin adamite . However it is increasingly being sold and distributed as cuproadamite, although it has yet to be officially acknowledged as a separate mineral. It contains an appreciable amount of copper and this usually colors the crystals a reddish purple to amethyst purple. The test is not foolproof however, as some adamites that contain little or no copper do not fluoresce either. Nearly all properties of cuproadamite are identical to adamite except typical color, density and fluorescence.
Color is typically reddish purple, but can be purple, red or even green.
Luster is adamantine. Transparency crystals are transparent to translucent. Cleavage is perfect in one direction. Fracture is conchoidal. Hardness is 3.5.
