Ludlamite Vs Petoskey Stone Fracture
Fracture is an important parameter when you compare Ludlamite and Petoskey Stone Physical Properties. It is necessary to understand the significance of these properties, before you compare Ludlamite Vs Petoskey Stone 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 Ludlamite is Gemstones (2009), Gemstones (2009), UnevenArthur Thomas and UnevenArthur Thomas.
