In quartz, a three-dimentional framework is developed through the complete sharing of oxygen by adjacent silicon atoms. Thus, all of the bonds in quartz are of the strong silicon-oxygen type. Consequently, quartz is hard, resistant to weathering, and does not have cleavage!
No. In minerology, cleavage is a feature, not a physical thing. Regardless, quartz does not possess the feature known as cleavage, meaning that it has no parallel broken surfaces. Rather, the feature that quartz can possess is called "fracture."
The major differences between quartz and calcite are hardness and cleavage. Quartz is about twice as hard as calcite. Quartz has little or at least very seldom any sort of obvious cleavage, whereas calcite has excellent and very obvious rhombohedral cleavage.
Quartz does not have cleavage because it lacks planes of weakness along which it breaks. Instead, quartz exhibits conchoidal fracture, breaking in a way that produces curved, shell-like pieces.
quartz will have conchidal fracture...plagioclase will have 2 sets of cleavage near 90 degrees and some striations quartz will have conchidal fracture...plagioclase will have 2 sets of cleavage near 90 degrees and some striations
No, quartz doesn't have distinctive cleavage, it will tend to break with a conchoidal fracture.
The cleavage of rose quartz is 2.65
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.
There is no broken parts in quartz, so Quartz does not have cleavage.

No, quartz has no cleavage.
Quartz has a conchoidal fracture. It does not have a cleavage plane.
