You got the main attributes (+2 lvl, +20% FCR) so it's good but got unlucky with the secondaries. Low on Strength, some way to perfection on the resistances. It's a nice Tiara but not worth a lot I suppose.
Perfect GG item would be sth like +2, +20% FCR, +30Str, +20 res, +25% mf or similar with Sockets or the like.
I am not experienced with this sort of thing but think you would get Mal or Ist for it.
My Necro would still love to have it. PM me if you want to get rid of it
