WebWater has a specific gravity of 1. Most common rock-forming minerals have a specific gravity between 2 and 3, For example, quartz has a specific gravity of 2.7. By contrast, some metallic minerals such as pyrite, native copper, and magnetite are more than twice as dense as quartz and thus are considered to have high specific gravity. WebIf a mineral exhibits different cleavage on different crystal planes, there will be two cleavage indicators separated by a semi-colon (;). For example, if the cleavage of a mineral is written as 1,2;3,1, than it has perfect cleavage in two directions, and poor cleavage in …

Technically, cleavage has to do with how strongly the molecules of a gemstone bind to each other. To put it in lay terms, it's much like wood grain. You can easily split a piece of wood along the grain, but going across the grain is much more difficult. Many gems have "cleavage planes, which vary across gem species. ind as 115 pdf mcaWebSo actually cleaving is a property all materials have, but depends on weak layers.
