Fracture is an important parameter when you compare Astrophyllite and Iolite Physical Properties. It is necessary to understand the significance of these properties, before you compare Astrophyllite Vs Iolite fracture.

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.
