Efficient Gem Crafting

  • Upgrade gems in bulk to save time
  • Death's Breath are only needed for high-level gems (Marquise and above)
  • Lower tier gems (below Marquise) can be combined without the Jeweller, directly from inventory
  • Flawless Royal gems are the highest level and cannot be upgraded further
  • Farm Act I Bounties for generous gem drops
  • Look for the "Hoarder" legendary gem to increase gold drops for crafting
  • Death's Breath can be farmed from Elite monsters

Gem Extractor

Remember that you can extract gems from socketed items without destroying the gem by using the Jeweller. This costs gold but preserves your valuable high-level gems.
