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 in the throes of 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.

Large gem production is bugged as of v50.07, and large gems can only be produced when specifying a gem type (see [http://www.bay12forums.com/smf/index.php?topic=180920.msg8452014#msg8452014 the forum post] for more information).

Finished gems have a particular cut, which doesn't affect the gem's value, only being an aesthetic feature. There are a total of 22 types of gem cuts in the game, and a gem may appear to have multiple cuts, such as a "square brilliant" or "tapered baguette" cut, but these combinations are actually distinct cuts (judging by the game's raws). Some gem cuts are also known as "cabochons", which have a basic "shape" cut typically as a rounded, polished stone. [[Gizzard stone]]s do not have cuts.

Gem sprite preview.png

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 crystals are required to make crystal glass goods. Cut gems can also be used to create windows and are often required as a source material for legendary artifacts. Gem-encrusted weapons and armor can be found in-game, but cannot be made in fortress mode. Stones, except the various types of clay, can also be cut into gems.

There are a total of 130 different kinds of gems, 127 excluding the three kinds of glass. Of these, 57 are ornamental, 58 semi-precious, 4 precious and 8 rare.

A large variety of cut gems can be brought by and requested from the dwarven caravan. You cannot import rough gems with the exception of raw glass, which human and dwarven caravans can bring.

Exactly 5% of all rough gems will be cut into a single 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 in the throes of 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 raw glass, which is the same as a lower-value, uncut gem.

Gizzard stones are found as a by-product when butchering some animals, and can be used like cut gems. Only a 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 or elk bird farm.

A killed amethyst man will, logically, drop a rough amethyst, but amethyst men are fairly rare. Forgotten beasts made of gem will leave a corpse, in some cases weighing thousands of Urists, but the corpse cannot be cut into gems or used in any other way.

You can also direct your dwarves to cut stone, shell, horn and ivory into a large gem which can be done at a craftsdwarf's workshop.

Value[edit]

Gems have a base value of 6 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 20. Items can be decorated (encrusted) with cut gems; all such decorations have a value of 20 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.

To give an example, a rough green zircon will be worth (6×20=) 120☼, a cut green zircon (20×20=) 400☼ and a masterwork large green zircon (10×20×2+30=) 430☼.

Dwarves who have preferences for certain gems and colors will have a higher-value perception of the items and walls encrusted with, or painted in, them.


In the premium version of the game, you can also quickly identify low-value uncut gems from the higher-value counterparts by the way they appear in-game - lower-value gems are smaller and do not have as many spikes.

High value and low value gems

Unlike other gems, diamonds can ignite if they come into contact with magma, and can burn for the better part of a year before finally wearing away.

Gem cuts[edit]

Finished gems have a particular cut, which doesn't affect the gem's value, only being an aesthetic feature. There are a total of 22 types of gem cuts in the game, and a gem may appear to have multiple cuts, such as a "square brilliant" or "tapered baguette" cut, but these combinations are actually distinct cuts (judging by the game's raws). Some gem cuts are also known as "cabochons", which have a basic "shape" cut typically as a rounded, polished stone. Gizzard stones do not have cuts.

Large gems (the finished good) are referred to as a singular version of their material such as "large single cut clear zircon" or "large cushion moonstone cabochon". Cut gems (the most common output of gem cutting which is used for decorating) are referred to as a plural version of their material such as "round brilliant cut peridots" or "cushion green diamond cabochons".

Rare gems[edit]

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, and in the gem-encrusted walls on the bottom-most cavern layer. Star sapphires and star rubies only occur within clusters of their peers.

All precious and rare gems may also be found in unusual volcanic walls.

Glass[edit]

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

Gems

Gem name Value Color Sprite Requires
green glass 2× ☼♦ Green glass sprite.png Cut green glass sprite.png bag full of sand
clear glass 5× ☼♦ Clear crystal glass.png Cut clear glass sprite.png bag full of sand + 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. Note that cut rock crystals can't be used to make crystal glass objects.

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

In real life[edit]

A gem is a mineral (or a mineral-like material) admired by a culture, often due to their beauty and durability (resistance to scratches), so that they have economic value in and of themselves.

Most gems are made of the same basic minerals found in common rocks; but their atoms are arranged into ordered patterns, called crystals, with drastic consequences to their appearance and material properties. For example, the same mineral quartz that looks so unremarkable in quartzite may form the strikingly geometric, beautifully translucent rock crystals, if it has the space to grow up slowly – in a crack or cavity within granite rock, for example.

  • Quartzite, an unremarkable stone.

  • Rock crystal growing inside a rock cavity. These are made of the same basic stuff as quartzite, only better arranged.

Each particular crystal has a stable angle between its faces, depending on the underlying atomic structure; quartz is hexagonal, while rock salt is cubic.

  • Hexagonal (left) and cubic (right) patterns of ordered mineral growth.

  • Rough rock crystals (quartz).

  • A large rock crystal, cut in an emerald-cut shape. Expert gem cutters will work with the natural planes of the crystal's structure, making them shiny and reflective.

  • Cubic rock salt crystals (click to embiggen).

A more drastic (and famous) example is carbon. The organic content of sedimentary rocks like bituminous coal may be pressured and heated into honeycomb layers, forming the metamorphic stone graphite (which we use in pencils, and dwarves use for long-lasting fires). That very same carbon may be shaped, with more pressure and less heat (when, for example, stricken by a meteorite), into the nested cubes known as diamonds.

Some non-mineral materials that have been sometimes considered "gems" include organic products like amber, coral, and pearl; and rocks (bundles of multiple minerals) like jet, jade and lapis lazuli. Of these, pearl only exists in DF as a placeholder, coral and amber in the most rudimentary of forms; but not as gemstones. Jet counts as a regular stone in DF, while jade (in various colors) and lapis lazuli are gemstones.
