Peridot exhibits a conchoidal fracture, meaning it breaks smoothly like glass rather than along defined planes. It does not possess cleavage, which is the tendency of some minerals to break along specific, flat surfaces. This characteristic contributes to peridot's unique appearance and durability in jewelry.
Peridot typically exhibits a conchoidal fracture, meaning it breaks in a smooth, curved manner like glass. It does not have a distinctive cleavage pattern due to its crystalline structure.
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.

Cleavage in two directions, one good, one distinct.
Fracture
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
the cleavage is Poor
Sapphire has a mixture of both cleavage and fracture characteristics. It has poor cleavage in one direction and conchoidal fracture, which means it breaks with smooth, curved surfaces similar to glass.
It has both cleavage and fracture.
