Sorry, I just noticed your post now. I think in theory you can get one, but it's probably a very rare event. I wouldn't rely on it. I tried this quest a few times in the beginning, but I thought it's not worth the time, since I got also often coins instead of gems. And since it's such a long quest, I thought it's much more profitable to quest for maps or food.

Don't worry, you will get some black gems (maybe even large ones) probably from mining or arena-collectable dragons - at least that is where I got my black gems from mostly. And from breeding Night dragons. I figured they are relatively easy to get by just breeding blue and purple dragons together, and each one trades for one small onyx, plus gives you a lof of bombs for the mine from evolution.
