Lookin' good. A few things, though...
Originally they had but a single spell.
As it stands, a ruby eyes could employ a 7d6 fireball or lightning bolt 2/day. In fact, it can open with a 7d6 fireball, wait a round, then unleash a 7d6 lightning bolt. Too powerful?

Theoretically, any magical spell could be put into the eyes (using enchant an item or permanency), but two factors limit the gems' magical power. The spells used in the gems are normally fourth level or lower; and spells tied to the "natural" power of the gem types are easier to make permanent.
If designing a unique variety of gem eyes, the DM should be careful which spells are put into the eyes. Since it takes at least a 9th-level magic-user to animate the dead, and an 11th-level magic-user to animate gem eyes, certain spells such as fireball or lightning bolt are simply too powerful for low-level adventures.
