This article is about an older version of DF.

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, including the various types of clay, can also be cut into gems.

A large variety of cut gems can be brought by and requested from the dwarven caravan. Rough gems must be procured by your own miners, you cannot import them. Human and dwarven caravans will also bring raw glass gems.

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 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 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 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[edit]

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.

See here or here for a sortable, print-friendly spreadsheet with all gems and their values.

Unlike other gems, diamonds can ignite if they come into contact with magma.

Gem Cuts[edit]

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[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. Star sapphires and rubies only occur within clusters of their peers.

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 Requires
green glass 2× ☼♦ bag full of sand
clear glass 5× ☼♦ bag full of sand + pearlash
crystal glass 10× ☼♦ 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 glassmakers can make from glass. See glass and glass industry for more information.

Bugs[edit]

Finished goods stockpiles will not accept items made from "gemstone" materials. As a consequence, the only reliable way to move large gems and gemstone crafts 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 dumping, and can be re-claimed later from the black hole 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.

Crafts and large gems cut from glass are not affected by the bug - the various "glass" materials are recognised by stockpiles correctly and they are stored and handled without problems.
