Can I get stones from lower lvl mobs?

I am lvl 75 archer, and i heard you could get stones from lower lvl mobs , which I farmed for over 4hrs lvl 65+ and 70+ and still have recieved any darn stones, so I gave up on that. However yesterday I got 1 helmet and 2 stones from 80+ mobs which are lvl 80 or higher +7 vit and +7 agi. Im not 80 yet. I got those in 4 hrs.

Now i am only using lower lvl chars from 25-45 but they all have gotten stones from mobs lower lvl. The lowest i remember was 5 lvls lower than me but other then that i hadn't paid much attention. I also get stones from mobs higher than me so I can only assume that stone drops are the same as any other drops and will occur if within 10 levels of yours.

Ok thanks bro;). I found out that I have also gotten a stone from a mob 2lvl's lower than me.
