∙ 15y agoRubies typically exhibit a conchoidal fracture, which means they break with smooth, curved surfaces similar to broken glass. Their cleavage is usually absent or very poor, meaning they do not break along distinct planes or directions.Ruby is a hard and durable stone, scoring 9 on the Mohs scale of mineral hardness, making it resistant to scratching and abrasion.

Gold does not have cleavage because it lacks a distinct pattern in which it breaks. Instead, gold exhibits a "hackly" or jagged fracture pattern when broken.
Zinc is a metal that exhibits a fracture rather than cleavage. Fracture refers to the way a mineral breaks when it is not along cleavage planes, while cleavage refers to the tendency of a mineral to break along flat planes.
Cleavage is the tendency of a mineral to break along planes of weak atomic bonding, resulting in smooth, flat surfaces, while fracture is the tendency of a mineral to break with rough, irregular surfaces. Cleavage results in smooth, reflective surfaces that reflect light, whereas fracture surfaces are dull and do not reflect light. Cleavage is a property that is characteristic of certain minerals and can be used for mineral identification, while fracture can vary depending on the specific conditions of the break and is less consistent across different minerals.
Gold exhibits a fracture rather than cleavage. Fracture describes how a material breaks when no preferential planes are present, in contrast to cleavage which denotes how a material breaks along specific planes determined by its crystal structure. Gold's fracture is typically uneven and jagged.
Minerals that have cleavage break along flat, smooth planes determined by their atomic structure, while minerals that have fracture break in uneven, irregular patterns. Cleavage is a property related to the internal atomic arrangement of a mineral, while fracture is the result of external forces causing a mineral to break.
There is no cleavage for the gemstone, ruby.
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.
Cleavage
It has both cleavage and fracture.
