I. The Metaphysical Reading
How the stone has been held.
Azurite is one of the classical stones of study and inner sight, worked with for concentrated reading, dream recall, and the drawing together of scattered thought into a single question. Practitioners keep it near the brow during long work and turn to it when a decision needs to be understood before it is made.

II. The Scientific Reading
What the lattice actually does.
Azurite is a secondary copper mineral that forms in the weathered zone of copper deposits, where descending carbonated groundwater reacts with primary copper sulphides. Its intense blue comes from the copper ion in a carbonate framework, and it slowly alters to green malachite when exposed to moist air over centuries. Ground azurite was the principal blue pigment in European tempera painting from the fifteenth to seventeenth centuries; the classic modern crystals come from Tsumeb in Namibia and Bisbee in Arizona.
