Cuprian Adamite, also known as Cuproadamite, is a green variety of
Adamite containing some copper that was originally reported from Cap Garonne Mine, Pradet, Var, Provence-Alpes-Côte d'Azur, France. This copper gives Cuprian Adamite its distinct pale to dark green color. Adamite is one of the best fluorescent minerals but Cuprian Adamite does not fluoresce because the copper kills the fluorescence. This is not a foolproof test as some Adamites that contain little or no copper do not fluoresce either. Nearly all other properties of Cuprian Adamite are identical to Adamite except typical color, density and fluorescence. Cuprian Adamite is an intermediate mineral between Adamite and Olivinite. There is a pink to purple variety of Adamite called Manganoan Adamite that is colored by its manganese content.
