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 no value in rough form. First they need to be cut in a jeweler's workshop. Cut gems have a base value of 5, which is multiplied by appropriate value modifier from the table below. Items can be decorated (encrusted) with cut gems; all such decorations have a value of 10 times the gem type's value multiplier.
