Well, here's another item, a simple one:
Night Light
This is a small, white orb. With a command word, it sheds light as the light spell. A second command word turns it off. Though not obvious, there is a tiny little button on the bottom of the orb. When this is pressed, it stays where it is, defying gravity as an Immovable Rod. When it is pressed, it can be moved.
Light transmutation and evocation; CL 5th; Craft Wondrous Item, levitate, light; Price: 6,000gp.
How about this? Modifying the stones a little.
Body Rings
Body rings are minor rings that go on different places of the body. They do not take up any of the normal spaces since their enchantments are generally considered minor. However, only one ring can be placed on the brow, tongue, ear, nose, finger [a normal ring, not a piercing], and toe [a normal ring, not a piercing].
Ring of Accuracy
This ring is placed on the finger. It does not count towards the normal only having two rings on the finger since its enhancement is so minor. It gives a +1 bonus on attack rolls.

Well, my original idea was to take the stones that palleomortis mentioned and have them absorbed into where they were supposed to work, but this idea came to mind. I'm surprised at how many I actually typed in. I was expecting to only have like five. Well, they're all pretty cheap, I might work on typing up their prices later. Let me know if this is a bad idea or whatever.
