Why does topaz have both cleavage and fracture?
Topaz has both cleavage and fracture because it has distinct planes of weakness along which it can break cleanly (cleavage), as well as areas where the mineral breaks irregularly and unevenly (fracture) when subjected to stress. Cleavage in topaz occurs along its basal plane due to its crystal structure, while fractures can happen when the stress applied is not along the cleavage planes.
What destroys Topaz?
Topaz are Insoluble in acids. It has great hardness and perfect basal cleavage. Even though, Topaz jewelry should not be ultrasonically cleaned; the vibration can cause incipient cleavage cracks to open, cleaving the stone. Some treated stones (particularly the expensive reds, pinks, violets and deep oranges, but not blue) are known to fade with prolonged exposure to direct sunlight.
What is the clevage of a sapphire?
Cleavage refers to how a mineral breaks and how the atoms are positioned. Cleavage is measured in the following ways: quality of cleavage, the number of sides exhibiting cleavage and the cleavage habit and in the case of a diamond it is all sides.

Does chalcopyrite have cleavage?
Chalcopyrite does not have cleavage. It typically exhibits a conchoidal fracture instead of cleavage planes.
Does blue topaz have cleavage?
Yes, it is perfect in one direction, basal.

Why a mineral such as topaz can display both cleavage and fracture?
Cleavage is when a mineral breaks into flat pieces. Fracture is when a mineral breaks into irregular pieces. Topaz atom bonds are weaker in some parts and stronger in others. When it is equally strong then it breaks into irregular pieces and if it all weak in a flat line then it will be flat.
