Small clusters of rough '''gems''' can be found almost anywhere while [[mining]]. After they have been mined by a [[miner]] and cut by a [[gem cutter]], a [[gem setter]] can use them to [[encrust]] [[furniture]], [[crafts]], and [[ammunition]]. In addition, raw [[rock crystal]]s are required to make crystal glass goods. '''Cut gems''' can also be used to create [[window]]s and are often required as a source material for [[legendary artifact]]s. Gem encrusted [[weapon]]s and [[armor]] can be found in game, but cannot be made in fortress mode.  Stones, including the various types of clay, can also be cut into gems.

The majority of these gems can be brought by and requested from the dwarven caravan, in both cut and rough form. Humans are capable of bringing [[glass]] gems, also in both forms. 

Exactly 5% of all rough gems will be cut into a single [[Useless_crap|craft]] or '''large gem''' (with 1 craft for every 8 large gems), and the same occurs with raw glass (but with different ratios - 33% of all jobs, producing 11 crafts for every 16 large gems). Note that these will ''replace'' a cut gem and cannot be used to encrust goods. The value of such crafts can easily reach hundreds, even several thousand in the case of valuable gems and good craftsdwarfship. A dwarf with a [[strange mood]] can take a single gem and cut it into a [[legendary artifact]] known as a "perfect gem" - this is simply a special name for an artifact large gem.

If you have any bags of sand, you can also manufacture [[Glass|raw glass]], which is the same as a lower-value, uncut gem.

[[Gizzard stone]]s are found as a by-product when butchering some animals, and can be used like cut gems. Only few animal species give gizzard stones, but each member of such a species butchered will yield one, which can lead to a decent supply when you manage to set up an ostrich farm.

== Value ==
Gems have base [[value]] of 3 in rough form, which is multiplied by the appropriate value modifier from the table below. They gain value after they are cut in a [[jeweler's workshop]]. Cut gems have a base value of 5. Items can be decorated (encrusted) with cut gems; all such decorations have a value of 10 times the gem type's value multiplier. See [[Gem cutting]] and [[Gem setting]]. Large gems have a base value of 10, and can also have a [[quality]] modifier which increases value.

== Varieties ==
Gems come in many varieties, with their own color and value multipliers:

Unlike other gems, diamonds can [[Fire|ignite]] if they come into contact with [[magma]].

== Gem Cuts ==

Finished gems have a particular cut. These cuts do not affect the gem's value. A gem can have multiple cuts, such as a "square brilliant" cut or "tapered baguette" cut. Some gem cuts are also known as "cabochons." Cabochons have a basic "shape" cut but not any more complicated cut. Gizzard stones do not have cuts.

List of cuts:
* baguette
* brilliant
* briolette
* cushion
* emerald
* marquise
* octagon
* oval
* pear
* point
* radiant
* rectangular
* round
* single
* square
* table
* tapered
* trillion

== Rare Gems ==
Faint yellow diamonds only appear in [[kimberlite]] (which itself only appears in [[gabbro]] layers) and sapphires and rubies only appear in [[bauxite]] (which occurs in any sedimentary layers). Colored diamonds only occur in pre-existing clusters of faint yellow diamonds. Star sapphires and rubies only occur within clusters of their peers.

== [[Glass]] ==
Raw glass is treated as an uncut gem.  There are three subtypes of raw glass (and, once cut, of cut glass gems):

Gems

{| style="border-spacing: 0"
|-
! Gem name
! Value

! Requires
|-
|green glass||2×||{{Raw Tile|☼♦|2:0}}||[[bag]] full of [[sand]]
|-
|clear glass||5×||{{Raw Tile|☼♦|3:0}}||[[bag]] full of [[sand]] + [[pearlash]]
|-
|crystal glass||10×||{{Raw Tile|☼♦|7:1}}||rough [[rock crystal]] + [[pearlash]]
|}

Making raw glass requires a dwarf with the [[glassmaking]] [[labor]] designated, and, just like working [[metal]], it also requires [[fuel]] (either [[coke]] or [[charcoal]]) at a normal glass furnace, or [[magma]] at a magma [[glass furnace]].  Like all gems, raw glass has no [[quality]] modifiers.

Raw gems are only one of the many things your [[glassmaker]]s can make from glass.  See [[glass]] and [[glass industry]] for more information.

== Bugs ==

No stockpile will accept large gems.  As a consequence, the only reliable way to move them is to select them for trading at a Trade Depot; after arriving at the Depot they cannot be moved elsewhere, except to a different Trade Depot.  Alternatively, they can be designated for [[Activity_zone#Garbage_dump|dumping]], and can be re-claimed later from the <s>black hole</s> garbage dump. (They will also be moved to a craft workshop - and left there - if they are selected to be decorated/encrusted there, but it is difficult to make this occur by player actions.)   This is presumably a bug.
