Usable by all classes. Precious gems can have zero, one, or more generic powers in addition to zero or one specific powers.
Level 1. Cursed-14. No burnout chance. The holder of this gem has the desire to possess all of the same type of stone (magical or not). Upon seeing any of the same type of stone, he must make a spiritual saving throw or he will do his best to gain possession of that gem. Any of this type of stone he already has in his possession he never willingly gives up. He can only get rid of this stone via a successful Remove Curse, as versus a 14th level.
Level 1. Each time the gem's specific power is used, the user will be suspected of any misdeed he could have committed during the 24 hours following the use of the gem. He need not have had any connection with the misdeed, but it must be at least possible for him to have done it. Alibis will tend to be disbelieved. The obvious guilt effect burns out whenever the gem's specific power does. The possessor of a gem of obvious guilt can rid himself of it without difficulty, although the effects of the gem's power are seldom so blatant as to raise suspicions in the user's mind.
Level 1. Burnout 20%. The gem is sensitized to the last person to possess it for 24 consecutive hours. He can, within 24 hours of last touching it, command the gem to return to him. Maximum range is 10 miles. A gem with both greed and return powers will not be willingly given up because of the burnout chance.
Level 1. No burnout chance. Sparklers increase a character's effective charisma when worn in plain sight. Wearing one sparkler adds +1, wearing two adds +2, 4 adds +3, 8 adds +4, etc. The charisma bonus applies to all charisma-based rolls. Clerics with vows of poverty cannot wear these and are not affected by them. No religion has a consistent policy against this; leave this up to the player.
Level N. Only a gem with a specific power defined as a mage spell (or spells) can be a Gem of Spell Levels +N. The user can modify the effect of the spell as per the mage system up to N/2 levels. These modifiers can only be used to affect the gem's powers, not spells cast by people. The modifiers applicable to a gem's powers should be stated if they are not clear from the spell description.
