All Diablo 4 Gems & Crafting Costs
As previously mentioned, gems in Diablo 4 are an important way to provide you with boosts to your stats regardless of your build or class, especially if you’re a beginner. The gems also change their effect depending on where you place them, so, for instance, placing them on your weapon may give you an attack buff, whereas placing it on your armor may grant you a passive buff.
Ultimately, gems are often easier to find or unlock than Legendary Aspects and can provide a more attainable way to survive the early game and they provide decent upgrade paths that grant effects that can be the difference between life and death in the game. So below, we’ve tabulated all of the gems in Diablo 4, as well as their effects and the cost of crafting and upgrading them by using the Jeweler NPC:
