Lapis lazuli Vs Tigers Eye Fracture
Fracture is an important parameter when you compare Lapis lazuli and Tigers Eye Physical Properties. It is necessary to understand the significance of these properties, before you compare Lapis lazuli Vs Tigers Eye 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 Lapis lazuli is ConchoidalWalter Schumann, Gemstones of the world (2001) and Uneven-Conchoidal. Tigers Eye fracture is Gems and Sixth Edition (2006).
Lapis lazuli Vs Tigers Eye Luster
A primary knowledge about Lapis lazuli vs Tigers Eye 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. Lapis lazuli exhibits Greasy and Vitreous luster. Tigers Eye, on other hand, exhibits Silky luster.
