Jewels +DEF and PUL rune in socketed armor

[jeckwild]

May be it was asked before, I couldn't search for the word PUL (4 letter limit on search)

Here goes:
I have Black Hades chaos armor with 3 sockets.
It has +180% defence now, ok.
Now, if I'm gonna put some PULs (+30% def) and/or +Defence (up to +64) jewels IN the armor itself (not anywhere else), would it have the same effect as if I put damage jewels in weapon? I.e. increasing BASE defence, not the +X%?

I'm a poor guy, I don't have pile of PULs to play with.
I also don't hack saved games and all this stuff for the reason that I'm lazy :D

Any info on this?

Thanks.
