Birefringence water ice crystal
WebBirefringence is a measure of a gem's double refraction. It serves as one of the principal ways gemologists can identify gems. Natural zircon (not to be confused with cubic zirconia) has been used to create convincing diamond imitations. However, this gem is doubly refractive and has a high birefringence. Webbirefringence: [noun] the refraction of light in an anisotropic material (such as calcite) in two slightly different directions to form two rays.

The ice. crystal. At standard atmospheric pressure and at temperatures near 0 °C, the ice crystal commonly takes the form of sheets or planes of oxygen atoms joined in a series of open hexagonal rings. The axis parallel to the hexagonal rings is termed the c -axis and coincides with the optical axis of the crystal structure.
WebAt ambient temperature and pressure, water molecules have a V shape. The two hydrogen atoms bond to the oxygen atom at a 105° angle. Common ice crystals are symmetrical and have a hexagonal pattern. Square crystals. Square ice crystals form at room temperature when squeezed between two layers of graphene.
