Adamite, also known as Manganadamite, is a pink to purple
variety of Adamite containing
some manganese. This manganese gives Manganoan Adamite its distinct pink to purple
color. Adamite is one of the best fluorescent minerals
but Manganoan Adamite does not fluoresce because the
manganese kills the fluorescence. This is not a foolproof
test as some Adamites that contain little or no manganese
do not fluoresce either. Nearly all other properties of Manganoan
Adamite are identical to Adamite except typical color, density and fluorescence.
There is a green
variety of Adamite called Cuprian
Adamite, or Cuproadamite, that
is colored by its copper content.
