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