This gemstone is a basic copper carbonate, vividly banded with two or more tones of green.
The beautiful green color comes from the copper contained in the stone (which is an altered form of copper), and water presence affects the shade: More water in the copper makes it lighter, and less makes it darker.
Nacre, itself often a synonym for mother of pearl, is composed of alternate layers of the aragonite form of calcium carbonate and conchiolin.

Verdigris, a basic copper acetate, and green earth, an iron-containing hydrosilicate, are equally represented among the watercolors tested—four each.
A copper green, in most cases probably verdigris, a basic copper acetate appears on ten fraktur.
The fact that many of the green areas have turned quite brown indicates the use of verdigris rather than copper resinate in those areas, since verdigris readily decomposes in the presence of water and heat to form a dark residue, cupric oxide, while copper resinate remains somewhat protected by the resinous medium.

ENVIRONMENT: Azurite is a secondary copper mineral and develops in the zone of alteration in all types of hydro-thermal replacement deposits, where it commonly occurs with malachite, limonite, and chalcopyrite.
The copper deposits in Arizona and Utah that yielded many fine specimens of Malachite also yielded outstanding specimens of Azurite.
