Question about Gems and effects

[Buckeye]

Ok so I am playing my Monk, level 45 now.

I picked up a Ywllow 1H Spear that does 142.5 DPS and a bunch of other good effects.
It came with a Square Ruby installed that says +14-28 Damage

Does that add to the DPS rating or is it just something like.. I hit the mob and did 100 damage, this gem adds +14-28 more damage.

I am debating pulling that Gem off and installing a Flawless Emerald which will do Crit Hit Damage increased %25. My Crit hit chance is only at 5% atm with damage at 50%

Any ideas ?

rubies add to the dps of a weapon. Seeing as how you only have a 5% chance of scoring a critical hit you will be better off just adding to your damage. Being a monk you may want to stack Dex to also increase your damage out put. seeing as how monks rely on speed that spear may be a bit slow. Now if you had a fast weapon you could throw a green gem on it and rely on your speed to catch that 5% more times then not.

The Spear is not bad.

142.5 DPS
85-129 Damage
1.33 Attack Per Second

+68 str
+89 dex
Increase Attack Speed +11%

My total Dex is 1120
Damage 1,782.26

I am hunting for better armor atm and what ever else might pop up. I am in Desolate Sands NM mode and nothing even comes close to stopping me. Blues/Yellows don't even slow me down. So doing ok for now.
