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