Zorite is a
silicate mineral
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust.

with the chemical formula of . It is named because of its pink color, after the Russian word "zoria" which refers to the rosy hue of the sky at dawn.

, and natrosilitite.
Crystallographically, zorite belongs in the orthorhombic group, which has 3 axes, a, b, and c that are of unequal lengths (a≠b≠c) that form 90° with each other. It also belongs in the point group 2/m2/m2/m. The state of aggregation for zorite is acicular. Zorite has perfect cleavage along the planes and , while having poor cleavage along the plane . Zorite is anisotropic, which means that the velocity of light is not the same in all directions. It belongs in the biaxial group, because it is an orthorhombic mineral. Under plane polarized light, zorite displays different colors depending on the angle that the light hits the mineral. This quality is called pleochroism and zorite is rose along the x-axis, colorless along the y-axis, and bluish along the z-axis. The index of refraction of zorite is 1.59, which is the velocity of light through vacuum over the velocity of light through zorite. Zorite is studied to better understand silicate structures.
In 2003, zorite was looked into to analyze the symmetry and topology of a family of three minerals found in Russia, Nenadkevichite, Labuntsovite, and Zorite. Zorite was also studied to comprehend how silicate structures change when an element is replaced, for example when the sodium
