Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Gyrolite is Uneven. Sillimanite fracture is Splintery.

Gyrolite Vs Sillimanite Luster

A primary knowledge about Gyrolite vs Sillimanite 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. Gyrolite exhibits Vitreous and Pearly luster. Sillimanite, on other hand, exhibits Vitreous, Subadamantine and Silky luster.
