Gems
Gems are a major source of GemStone IV's treasure system. More often than not, the value of the gems found will exceed the silver found in a given hunt. The value of gems can range from 5 silver coins to more than 10,000.
There is a vast array of different types of gems that can be found within Elanthia, and hunting in different areas have different gems to offer. For example, a Selanthan bloodjewel can only be found in the areas around River's Rest and Solhaven.
Gems can be appraised using the APPRAISE verb. The value and quality of a gem can be increased by using the bard song, Purification Song (1104). Some gems can be prepared to hold spells to be released at a later date, such as through the spells Magic Item Creation (420) and Holy Receptacle (325).
Every gem found through the treasure system has a show description. Some gems, such as those found in Zul Logoth's caves (not those found on the creatures), do not have a show attached to them.
