Gypsum has cleavage, which means it tends to break along flat surfaces.
Gypsum exhibits perfect cleavage in one direction, which allows it to be easily split into thin sheets. This characteristic cleavage is due to its layered crystal structure, primarily composed of calcium sulfate dihydrate. When broken, gypsum tends to fracture along these planes, producing smooth, flat surfaces.
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.
Gypsum has a brittle fracture with a conchoidal or uneven break. It tends to break into irregular, sharp pieces when fractured.

Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.
