Olivine cleaves. It looks like fracture, but under a magnifying lens you can see the tiny, crystal-like cleavage.
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
yes rutile has cleavage-distinct (100) yes rutile has fracture
Azurite does not have cleavage, but it exhibits a conchoidal fracture, meaning it breaks into smooth, curved surfaces similar to glass.
No, it has no preferred fracture or cleavage.
Olivine does not have cleavage. It exhibits a granular or irregular fracture pattern instead of cleavage planes.
Olivine typically exhibits a concoidal fracture, which means it breaks with smooth, curved surfaces rather than along defined planes. This characteristic fracture is due to its crystal structure, which does not have distinct cleavage planes. In addition to its fracture, olivine is often recognized by its glassy luster and various shades of green.
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.

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: uneven fracture, and perfect cleavage in three directions.
It has both cleavage and fracture.
