cleavage plane

The cleavage planes are at right angles to one another.

Diamond has a cleavage plane and is therefore more fragile in some orientations than others.

A breakage in diamonds that is not parallel to the cleavage plane is referred to as a fracture.

However, water infiltrates along cleavage planes and the weathering advances easily up to the mineral core.

The following cleavage planes are centered on this axis and result in the two halves being mirror images of one another.

This results in conchoidal fractures, a characteristic of all minerals with no cleavage planes.

The name is from the Greek for "straight fracture," because its two cleavage planes are at right angles to each other.

This structure does lead to minerals in this group having one strong cleavage plane.

The cleavage plane can be found either subcorneal or within the upper stratum granulosum.

This significant density difference is because of the presence of epoxy between the cleavage planes.
