Anorthite is a calcium-rich mineral that occurs in many basic igneous rocks. It is the calcium end member of the plagioclase feldspar series. It has a brittle tenacity and its cleavage is perfect in one and good in another direction.
Anorthite symbolizes formal, conservative, passion, happiness, empowerment, clarity, freshness, and integrity.
Let us learn more about Anorthite.
Anorthite is a common rock-forming mineral that contains a high proportion of calcium to sodium. It has a triclinic crystal system with prismatic structure and transparent to translucent diaphaneity.
Anorthite is strongly associated with the crown chakra and it helps to open up and balance the crown chakra. It helps the wearer to clear up emotional insecurities, promote mental peace, and heighten the state of consciousness.
Anorthite was first described in 1823 and was named by Gustav Rose, a German mineralogist, from the Greek word αν and oρθός which means "less than straight, not perpendicular". Its name was given in allusion to the odd angles at which crystals grow. The type localities of Anorthite are Monte Somma and Valle di Fassa, Italy.
Anorthite is the rarest member of the plagioclase feldspar group that occurs mostly in mafic igneous rocks and metamorphic rocks of granulite facies. It also occurs in metamorphosed carbonate rocks and corundum deposits.
The chemical formula of Anorthite is CaAl2Si2O8. It has a hardness of 6 according to the Mohs scale and vitreous luster.
Although Anorthite is very rare, it can cost from around $20 to $80 per carat.
