A pearl does not exhibit cleavage; instead, it tends to break in a way that is referred to as fracture. This is because pearls are composed of aragonite or calcite in a conchiolin matrix, which gives them an irregular internal structure. As a result, when subjected to stress, pearls typically fracture rather than split along specific planes like minerals that exhibit cleavage.
Conchoidal Fracture. Clevage is impossible in a pearl
Clevage-a flat cut. Fracture-a cut that hes bumps in it.

Physical properties like clevage,fracture,color, ect.
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.
When minerals do not display cleavage, they are said to have a fracture. Fracture describes the way a mineral breaks when it does not have cleavage planes. This can result in irregular or random patterns of breakage.
There is no broken parts in quartz, so Quartz does not have cleavage.
A break and a fracture are exactly the same the same thing. The word "fracture" is just a medical term for a break.
A simple fracture - results in a 'clean' break across the bone. A green-stick fracture is an incomplete break.

No, a mineral cannot have both fracture and cleavage. Fracture refers to the way a mineral breaks when no cleavage is present, whereas cleavage describes the way a mineral breaks along its planes of weakness. Minerals either exhibit fracture or cleavage, but not both at the same time.
A diamond fracture is a break or a crack in the stone.
