  • You can sell a gem with 20% quality to an NPC to get 1 Gemcutter's Prism. You can also sell several gems with total quality of at least 40% to get one.
  • Since GCPs are quite valuable, it might be worth it to pick up the gems you find that have quality - to trade them for GCPs.
  • Gemcutter's Prisms are quite expensive and it is only worth using them in the endgame, when you can get a gem to 20% quality. A few points of quality on a gem don't matter as much as a Prism's monetary value. It is better to either just buy a high quality gem or use the recipe described below.
  • Upgrade gem quality You can increase the quality of a gem to up to 20%. For different gems, quality gives different bonuses. For some gems, it might not be worth it to increase the quality at all. For example - aura gems get increased AoE radius with quality, which doesn't matter while you are playing solo.
  • A cost efficient way to get your gems to 20% quality is to first level them up to level 20 (max). If you sell a level 20 gem along with 1 Gemcutter's Prism to an NPC, you will get the same gem back with 20% quality, but its level will be back to 1. That way you only need 1 GCP to get a gem to maximum quality. Of course, this way you will have to level the gem again.
