I. The Metaphysical Reading
How the stone has been held.
Natrolite is held as a stone of high vibration, worked with in meditation to open the upper chakras and to encourage clear inner sight. Its slender radiating needles are read as symbols of directed, focused attention.

II. The Scientific Reading
What the lattice actually does.
Natrolite is a sodium-rich zeolite that crystallizes in slender orthorhombic prisms, often forming radiating sprays in the vesicles of basaltic and nepheline-syenite rocks. Its open aluminosilicate framework contains channels of loosely bound water and exchangeable sodium ions.
