The occurrence of a gemstone breaking into two or more pieces during the cutting or polishing process. Naturally occurring impurities in the stones increase the likelihood that a stone will break apart.
Investopedia Says:
Gemstones - especially large ones - are very rare. When large gemstones are found, they are usually sold to investors who pay to have the stones cut and polished. A large gemstone that is successfully cut and polished is many times more valuable than an unpolished stone of similar size. However, gemstone investments include the substantial risk that a stone will cleave during the cutting or polishing process, causing a substantial decrease in its value.

A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat endface, perpendicular to the longitudinal axis of the fiber. Since there are no crystalline planes in glass, this process is not cleavage in the crystallographic sense of the word, although the techniques used and the finished result are quite similar.
A cleave is made by first introducing a microscopic fracture ("nick") into the fiber with a special tool, called a cleaving tool, which has a sharp blade of some hard material, such as diamond, sapphire, or tungsten carbide. If proper tension is applied to the fiber as the nick is made, or immediately afterward (this may be done by the cleaving tool in some designs, or manually in other designs), the fracture will propagate in a controlled fashion, creating the desired endface.
A good cleave is required for a successful splice of an optical fiber, whether by fusion or mechanical means. Also, some types of fiber-optic connectors do not employ abrasives and polishers. Instead, they use some type of cleaving technique to trim the fiber to its proper length, and produce a smooth, flat perpendicular endface.
High-precision optical fiber cleavers are commercially available through a small number of specialized manufacturers, such as Nyfors Teknologi AB, which usually also supplies other fusion splicing accessories such as fiber optic recoaters and stripping and preparation equipment.
