Sediment grains move into more compact arrangements, ductile grains (such as mica grains) are deformed, and pore space is reduced. Gems endure through time as they are resistant to chemical alteration, are sufficiently hard to retain a good polish and are not easily chipped or broken. , Lithification follows closely on compaction, as increased temperatures at depth hasten deposition of cement that binds the grains together.  These grains can be classified into several different categories based on their mineral composition: Matrix is very fine material, which is present within interstitial pore space between the framework grains.

Sandstone is formed in diverse environments where huge quantities of sand accumulate as a result of water or wind movements. Mining involves mining various ores throughout the world with a Pickaxe to acquire Crafting Materials in the form of Ingots or Gems.  Because of the hardness of individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones, for sharpening blades and other implements.
