Topaz Vs Lapis lazuli Fracture
Fracture is an important parameter when you compare Topaz and Lapis lazuli Physical Properties. It is necessary to understand the significance of these properties, before you compare Topaz Vs Lapis lazuli 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 Topaz is Subconchoidal, Uneven, ConchoidalArthur Thomas, Gemstones (2009) and Brittle. Lapis lazuli fracture is Uneven-Conchoidal, ConchoidalWalter Schumann and Gemstones of the world (2001).
Topaz Vs Lapis lazuli Luster
A primary knowledge about Topaz vs Lapis lazuli 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. Topaz exhibits Vitreous luster. Lapis lazuli, on other hand, exhibits Vitreous and Greasy luster.
