Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Chlorastrolite is Granular.

A primary knowledge about Chlorastrolite vs Sphalerite luster is useful in apparent identifications of these gemstones.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Chlorastrolite exhibits Chatoyant luster.
