Londonite Vs Chondrodite Fracture
Fracture is an important parameter when you compare Londonite and Chondrodite Physical Properties. It is necessary to understand the significance of these properties, before you compare Londonite Vs Chondrodite 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 Londonite is Brittle, Conchoidal, ConchoidalAnthony et al, ConchoidalAnthony et al, Handbook of mineralogy (2001) and Handbook of mineralogy (2001). Chondrodite fracture is Brittle, Conchoidal, ConchoidalArthur Thomas, Gemstones (2009), Uneven and Uneven.
Londonite Vs Chondrodite Luster
A primary knowledge about Londonite vs Chondrodite 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. Londonite exhibits Vitreous luster. Chondrodite, on other hand, exhibits Greasy and Vitreous luster.
