This is known as conchoidal fracture.
The difference between a mineral that has cleavage and one that has fracture is that cleavage is the tendency of some minerals to brake along flat surfaces and fracture is the tendency of some minerals to brake unevenly along curved or irregular surfaces.
Cleavage
the manner in which a mineral breaks along either curved or irregular surfaces is called a FRACTURE.

The mineral quartz show the property of fracture. it breaks along a curved surface. this kind of fracture is called conchoidal fracture. In math the quartz is x3.
The property is referred to as cleavage or fracture, the tendency, or lack of tendency, of a mineral to break along planes of weakness. Some minerals have multiple planes of cleavage. Some have none, and are said to exhibit fracture.Cleavage is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.fracture is the tendency of a mineral to break into irregular pieces. Some minerals such as quartz break into pieces with curved surfaces. Other minerals may break differently-perhaps into splinters or into rough or jagged pieces. In a mineral that displays fracture, the bonds that join the atoms are fairly equal in strength in all directions. The mineral does not break along flat surfaces because there are no particular directions ofweakness in its crystal structure.
a hexagonal prism has 0 curved surfaces
2 flat and 1 curved
This is known as conchoidal fracture.
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
A triangular prism contains zero curved and 5 flat surfaces.
