True resurrection

True resurrection is a conjuration spell that revives the dead, even those whose bodies have been destroyed.

Effect
This spell works in the same manner as raise dead, except the cleric can resurrect a creature who has been dead up to 10 years per caster level. This spell can even bring back creatures whose bodies have been wholly destroyed, provided you unambiguously identify the deceased in some fashion (reciting the deceased's time and place of birth or death is the most common method).

Upon completion of the spell, the creature is immediately restored to full hit points, vigor, and health, with no loss of level (or Constitution point) or prepared spells.

You can revive someone killed by a death effect or someone who has been turned into an undead creature and then destroyed.

Even true resurrection can't restore to life a creature who has died of old age.

Material Components
A sprinkle of holy water and a diamond worth at least 5,000 gp.
