Diablo 4 Gem Upgrades Guide

Gems are your best friends.

To be successful as a fighter in Diablo 4, you must be excellent at crafting. All those gems you find during your adventures have a meaning, as they give your gear additional bonuses. Every type of equipment has a socket for a gem, which I found very useful. But the precious rocks I uncovered were not very powerful. This Diablo 4 gem upgrades guide will help you improve your gear to make you stronger.

How to upgrade Gems in Diablo IV

In Diablo 4, each gem can be upgraded several times, but you need to gather resources for gems recipes and to unlock Jeweler in the city. To unlock Jeweler in Kyovashad, you must complete a priority quest. You'll then be able to upgrade to chipped gems. For better quality gems, you'll have to level up your hero up to level 70 to get a chance to upgrade gems in Diablo IV fully. Those gems are:

  • Emerald (green gem)
  • Ruby (red gem)
  • Topaz (orange gem)
  • Amethyst (purple gem)
  • Diamond (white gem)
  • Sapphire (blue gem)
  • Skull (it's a human skull, you'll recognize it when you see it)

What's the highest Gem upgrade in Diablo IV

Screenshot by Pro Game Guides

The highest gem upgrade in Diablo 4 is the royal type of gem. That is the fifth level of gem upgrade, for which you need to reach level 60 with your character and gather the necessary resources. To reach level 60, you must complete the campaign and reach the end game. Only then can you upgrade your gems to royal level.
