There are two ways to improve the quality of Diablo 4 gems you find. Firstly, levelling up will allow you to Diablo IV Gold find better gems – for example, at around Level 15 you’ll be finding Crude gems, but by Level 20 you should start getting Chipped gems and so on. However, if you’re wondering how to store all your gems, make sure you visit your Stash in a city to store them – you can easily fast travel back here to collect any too. However, developer Blizzard has confirmed that gems will be moving to the Materials tab, taking them out of your inventory altogether. This update is expected to arrive towards the end of this year around Season 2.
The second way to get higher quality gems is to visit a Jeweler in a town, although you won’t have access to Jewelers until you’ve completed a specific priority quest.
Once you reach Level 20, visit a Diablo 4 Jeweler in a town and complete the ‘Gem Crafting’ priority quest. This walks you through the Jeweler’s ‘Craft Gems’ service to combine three gems of the same type and quality into one higher level gem with better stats in exchange for Gold. For example, three Chipped Amethysts could be combined into one Amethyst.
After completing the quest, you can freely combine gems at any Jeweler. This process also takes into account any gems you've placed in your Stash so you don't need to fetch them first. Now that you’ve collected some gems and hopefully have combined them into better ones, you need to socket them into your gear to improve it.
If you have any gear in your inventory with empty socket(s), indicated by a black circle over the top of the icon, then the process to socket gems in Diablo 4 is a straightforward one. Simply hover over the gem you want to apply in your inventory and follow the Socket prompt, which will highlight any equipment that can receive the gem, then select the item to insert the gem. It’s free and doing this is a key part of perfecting you class builds buy Diablo IV Items , so make sure you gather up the gems you need and slot them as soon as possible.
