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