Amazonite is a blue-green variety of the mineral microline,belonging to the potassium feldspar group.
Mineral class: Tectosilicate
Crystal system: Triclinic
Rock formation: it typically forms in coarse-grained igneous rocks like pegmatites and plutonic granites. The slow cooling of magma in these environments allows the crystals to grow large.
The blue-green colour is caused by trace amounts of lead and water within the
crystal structure.
Hardness: 6-6.5 on the MOHs scale
