There are very few gems that are used in specific quests. One quest in Baldur's Gate 1 involves stealing a Rogue Stone, and another involves killing a monster for a Sphene Gem (and you can give the quest person any Sphene Gem you might happen to have). There are other gems not described on this page with very specific names that you can generally tell are required for quests (Glittering Beljuril Gemstone). The rest can simply be sold.
