40d:Gem

Small clusters of gems can be found strewn throughout the fortress. Gems can used to encrust furniture, weapons, armor and ammunition, to create windows and as a source material for legendary artifacts.

Value

Gems have base value of 3 in rough form, which is multiplied by 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 (?unverified?) times the gem type's value multiplier.

Glass

• green glass, x2 value, requires only a bag full of sand
• clear glass, x5 value, requires pearlash as well as a bag full of sand
• crystal glass, x10 value, requires pearlash and rock crystal

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 large, spiked balls or giant axes. However, this appears to requires a Glass Bar, which is not possible to create at the current time.

Outside of Metal and Wood, Glass is the only readily available material to create Cages out of, as well.
