lazurite
Azure gemstone component
Lazurite is a deep blue mineral that forms the primary component of lapis lazuli, the semiprecious stone prized since antiquity for jewelry and pigments.
The intense blue color comes from sulfur in its crystal structure.
Crushed lapis lazuli produced the pigment ultramarine, once more valuable than gold: The painter reserved his precious lazurite blue for the Virgin's robes.
