Lapis lazuli
is an opaque to translucent blue, violet-blue, or greenish-blue semi
precious gemstone composed mainly of lazurite and calcite. It is
often dyed to deepen and improve its color and contains the minerals
calcite (which decreases its value), pyrite (which can increase its
value), and sodalite. The rich blue color is due to the sulfur
inherent in the structure of lazurite. Lazurite is resistant to
atmospheric gases, is lightfast and possesses good hiding power. It
is durable with all other permanent pigments.
Lapis Lazuli is said to cleanse the mental body while releasing old
karmic patterns. Being a spiritual stone, it allows spiritual energy
to be absorbed in the aura. Lazurite is currently extracted from two
regions of the former Soviet Union: Malobystrinskoye deposit of the
south Baikal region, and the Lyadzhvardarinskoye deposit in the
southwestern Pamirs Mountains. Other significant deposits of
lazurite are found at Ovalle, Cordillera, Chile; Mt. Vesuvius,
Italy; Cascade Canyon, San Bernardino Mountains and Ontario Peak,
California, Colorado, U.S.A.
