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 observed in Cordierite is Brittle, Conchoidal and Subconchoidal. Leucite fracture is Brittle, Conchoidal, ConchoidalArthur Thomas and Gemstones (2009).

A primary knowledge about Cordierite vs Leucite luster is useful in apparent identifications of these gemstones. Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Cordierite exhibits Greasy and Vitreous luster. Leucite, on other hand, exhibits Vitreous luster.
