Tourmaline Vs Neptunite Fracture

Fracture is an important parameter when you compare Tourmaline and Neptunite Physical Properties.

Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Tourmaline is Conchoidal, ConchoidalArthur Thomas, Gemstones (2009) and Uneven.
