Fracture observed in Nephrite is Gemstones (2009), Granular, Granular, Splintery and Splintery. Biotite fracture is Even, Uneven, White and Yellow.

Nephrite Vs Biotite Luster

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