A '''gem cutter''' is the profession of a dwarf whose highest skill is in gem cutting. Performed at a [[Jeweler%27s_workshop|Jeweler's workshop]], gem cutting is the basis of the [[gem industry]], turning mildly valuable [[gem]] clusters you find as you [[mining|mine]] away rock into valuable [[decoration]]s for [[furniture]] and [[Finished goods|trade good]]s. It is the counterpart to [[gem setting]]; together, the two belong to the category profession of the [[Jeweler]], and indeed if a dwarf has a relatively balanced skill level in both, they will be known as a Jeweler. (More often than not, migrants who are skilled in gem cutting will also be similarly skilled in gem setting.)

Large amounts of mining are bound to produce dozens of rough gems, so gem cutting is a method of developing [[wealth]] quickly, [[Quickstart guide#Gemcutting and Trinkets|especially]] for new players. Cutting and encrusting with a gem more than triples the [[value]] of the rough gem, which is then multiplied by a [[quality]] modifier based on the gem setter's skill. A masterwork gem decoration is worth 40x the value of the original rough gem. 

Cutting a [[gem]] can result in a cut gem, a large gem, or a gem [[craft]]. Cut gems are the most likely, and are used by a gem setter in creating gem [[window]]s and [[encrust]]ing other objects. Large gems and gem crafts are only created one-third of the time. Large gems are currently only useful for [[trade]]. The skill level of a gem cutter affects the cutting speed, and quality of large gems and gem crafts, but not the quantity of crafts produced<sup>[[DF2012 talk:Gem_cutter|1]]</sup>.

=== Training ===
Gem cutters can cut not only gems proper, but regular [[stone]] and [[glass]] as well. Although cut stone is next to worthless, it still provides experience points, and can be used to keep a jeweler busy while you mine out a fresh batch of gems. It is also the only way to decorate with stone, and an easy way to create [[window|windows]] without [[fuel]] or [[sand]]. However, with a [[magma]] and a sand source, raw green glass can be mass-produced, which is worth the exact same as the cheapest gems.

=== Automation / Advanced Control ===

The v50 Jeweler's Workshop comes with a general "Cut Gem" job that by default will use any rough gem a jeweler can find. After the job has been created the gem type can be specified by modifying the job, in the [[Premium version]] this can be done by clicking on the magnifying glass icon and selecting the rough gem type here. [[DFHack]] is no longer needed for proper automation of gem cutting. On the other hand, it will be more difficult to cut anything but a specific type of gem, most often [[rock crystal]], which is needed for [[glass|crystal glass]] production. The easiest way to do this is to use a linked [[stockpile]] that does not accept the gem type you want to preserve.



{{D for Dwarf}}

How one cuts gems without a chisel or any other tool is a source of much study. The predominant theory is that dwarven teeth, sharpened and conditioned by years of eating the tough flesh of [[plump helmet|plump helmets]], function as a crude cutting tool hard enough to cut diamonds. This is followed by polishing the gem using the tough fibers of their beards, just as it's used to smooth surfaces.
