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. Streak is white. Associated Minerals are adamite , limonite , conichalcite , smithsonite , aragonite , calcite , and other oxidation zone minerals. Best Field Indicators are color, density, non-fluorescences, associations and crystal habits.
