Getting skill upgrades also requires reaching a certain level. The bottom row skills (such as Summon Demon, Reflect, and Death Blow) require something like Lv34-36 to acquire. So until then, you can only get it up to 13.
Gems are ingredients in enchantment formulas, just the same as herbs are for potions.
