Imbued gems are only used to a very small percentage on JC, mostly they are used for cultural smiting. Only cultural armor pieces with imbued gems do add to stats, the downside is that imbued gems make the armor to be used by followers of the appropriate deity only.
Every deity has a certain gem he favours so every race is able to use imbued gems for all the deities that race may choose to follow - even if the character follows another deity. But an imbue itself can only be done by a cleric for the gem of the deity he follows.
