Freezing Band Stats

Now, to preface this it could very well be my own ignorance.
I linked a freezing band from my level 40 Mage (no +spellpower) to my friends level 12 warlock. On my screen it says the +Frost damage is 21, and on his it says 14.
I'm not totally sure if memory serves that there would be a reason that because its more applicable to me- or that I'm higher level- that it would cause that difference in perception.
