Jewels are used on an item from your inventory (right-click the jewel, then click the item), or as an ingredient in the Chaos Machine. Most of them also come as bundles, which you can unpack to get the jewels back.

Where they drop
Monsters drop Jewels of Bless, Soul, Life, Chaos and Creation as part of their normal drops; how often depends on the monster's level. Many bosses also drop one to four of them at random every time they die: the bosses of Kalima 4 to 7, the field bosses Ice Queen, Balrog, Hydra and Hell Maine, the Land of Trials bosses, the Dark Elf in Balgass Refuge, Medusa and Selupan. See the Bosses guide for how many each one drops.
