It depends on what kind. The bigger carats are actually part of the main vain and are considered cleavages while the smaller ones are actually fractures
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.
Diamonds typically cleave rather than fracture due to their crystalline structure. Cleavage in diamonds occurs along specific planes, allowing them to break cleanly and predictably. This property is a result of the strong covalent bonds between carbon atoms in their crystal lattice. In contrast, fracture refers to an irregular break, which is less common in diamonds due to their cleavage characteristics.
A diamond's cleavage refers to the tendency of the diamond to split along certain planes of weakness due to its crystal structure. Fracture in a diamond occurs when it breaks irregularly, without following a distinct plane of weakness. Both cleavage and fracture can affect the value and durability of a diamond.
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.

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.
