Gems are useful for smithing, as they increase the skill by quite a bit. They can be smithed into jewelry which can then be enchanted with properties that buff certain attributes (fortify light armor, extra sneaking or lockpicking percentage, etc). Also, some gems are used during quests. For example, there is an Argonian in Riften who will ask you to find three Flawless Amethysts so that he can make a wedding ring for his lover. As you mentioned, they can also be sold for a fair amount of gold.
