Nephrite Vs Sapphire Fracture

Fracture is an important parameter when you compare Nephrite and Sapphire Physical Properties. It is necessary to understand the significance of these properties, before you compare Nephrite Vs Sapphire fracture.

Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Nephrite is Splintery and Granular.

Nephrite Vs Sapphire Luster

A primary knowledge about Nephrite vs Sapphire 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. Nephrite exhibits Vitreous and Greasy luster. Sapphire, on other hand, exhibits Vitreous and Adamantine luster.
