Unlocking the Jeweler in Diablo 4 is a straightforward affair; simply reach level 20, and an Urgent Quest will guide you to the one in Kyovashad. The Jeweler can also be found in every major settlement and even a few minor ones, as well. If this is your first time playing, you will likely still be working out of the first hub settlement of Kyovashad at that level, so you won't have far to go to start making the most of those Gems.

The Jeweler offers a series of services, all of which will be essential as you approach Diablo 4's intimidating Endgame. The most common of which will be the Crafting of Gems, which allows rougher rocks to be refined into a single, more startling piece. Sockets can be added to certain items that lack them, allowing an additional place to slot a Gem. Gems can also be Unsocketed for a fee, returning it to your Inventory and allowing the placement of another.

Gems come in the following flavours, offering different benefits for different builds.
