Andalusite Vs Amblygonite Fracture
Fracture is an important parameter when you compare Andalusite and Amblygonite Physical Properties. It is necessary to understand the significance of these properties, before you compare Andalusite Vs Amblygonite fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage. 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 Andalusite is Gemstones (2009), Splintery, Subconchoidal, Subconchoidal, Uneven, Uneven and UnevenArthur Thomas. Amblygonite fracture is ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009), Gemstones (2009), Irregular/uneven, Sub-Conchoidal, Sub-Conchoidal and Uneven.
