Gem

From DwarfFortressWiki

Small clusters of rough gems can be found strewn throughout the mountain. Cut gems can be used to encrust furniture, crafts, weapons, armor and ammunition, to create windows and as a source material for legendary artifacts. In addition, raw rock crystals are required to make crystal glass goods. Large gems are a byproduct of cutting and can not be processed further. They have a high base value for an item(10x) and can easily reach hundreds, even thousands depending on the gem. Artifact large gems made from precious jewels will go for around 50,000.

[edit] 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.

[edit] Varieties

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

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

[edit] 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.

[edit] Glass

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

Like working metal, making glass requires fuel, either coke or charcoal at a normal glass furnace, or magma at a magma glass furnace.

Glass has other uses than as a mere gem, as glass can be used as (a rather odd looking) stone for most buildings, such as Tables or Doors. In addition, Glass can be converted into Trap components, such as spiked balls or giant axe blades. Glass trap components have the same weapon damage as wood or silver (50%).

Glass windows can be made at a glass furnace as an alternative to making windows from gems.

Outside of Metal and Wood, Glass is the only readily available material to create Cages (actually terrariums or aquariums) out of, as well.
