Grossular Vs Apophyllite KF Fracture
Fracture is an important parameter when you compare Grossular and Apophyllite KF Physical Properties. It is necessary to understand the significance of these properties, before you compare Grossular Vs Apophyllite KF 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 Grossular is Conchoidal, Uneven, ConchoidalArthur Thomas, Gemstones (2009), Conchoidal and Brittle. Apophyllite KF fracture is Uneven, Brittle, Uneven, Brittle and Uneven.
Grossular Vs Apophyllite KF Luster
A primary knowledge about Grossular vs Apophyllite KF 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. Grossular exhibits Greasy and Vitreous luster. Apophyllite KF, on other hand, exhibits Vitreous and Pearly luster.
