Uncut gems are how every skill, support, and persistent buff in Path of Exile 2 gets unlocked — you can't run a single ability without them. The short answer: Uncut Skill Gems, Uncut Support Gems, and Uncut Spirit Gems all drop randomly from slain monsters, and the level of the gem that drops scales with the area level you're farming. Early gems come free from quest rewards; the coveted Level 20 Uncut Skill Gems only fall in Tier 15–16 maps juiced with the right modifiers. This guide breaks down exactly where each type comes from, the fastest early sources, and how to target Level 20 gems in the endgame — verified against the official tooltips and current 0.5.4 economy.

Key Takeaways
- Uncut gems drop from monsters, and the gem level equals (roughly) the monster/area level — so higher zones drop higher-level gems.
- Three types: Uncut Skill Gems (your abilities), Uncut Support Gems (modifiers), and Uncut Spirit Gems (persistent buffs, heralds, auras).
- In-game tooltip (GGG): an Uncut Skill Gem "Creates a Skill Gem or Levels an existing gem to Level X" — so it doubles as a gem-leveling item, not just a one-time unlock.
- Uncut Skill Gems have a world drop level of 4 (Level 1 for the quest-reward version) and scale up to 20 tiers.
- Level 20 Uncut Skill Gems are extremely rare — chase them in T15–T16 maps that are corrupted and irradiated, on Atlas nodes with "+1 to Level of Monsters."
- Faster than grinding? Buy the exact gem you need on the Currency Exchange or via trade — often cheaper than dozens of dead-end maps.
What Are Uncut Gems in PoE2?
In Path of Exile 2, you don't find finished skill gems on the ground — you find uncut ones and engrave the ability you want into them. There are three families, and knowing which is which saves you hours of confusion:
- Uncut Skill Gem — creates an active Skill Gem (your main abilities: attacks, spells, minions, totems). Right-click it and pick any skill your class can use, at that gem's level or lower.
- Uncut Support Gem — creates a Support Gem that modifies a linked skill (added damage, extra projectiles, faster casting, etc.).
- Uncut Spirit Gem — creates a persistent / meta skill that runs off your Spirit reserve: heralds, auras, and buffs like Grim Feast.
The exact in-game text on an Uncut Skill Gem reads:
"Creates a Skill Gem or Level an existing gem to Level X. Right Click to engrave a Skill Gem."

That second half matters and trips up a lot of players: an Uncut Skill Gem doesn't only unlock new skills — you can use a higher-level Uncut Skill Gem to level up a skill you already have up to its Level X. So a Level 12 Uncut Skill Gem can bump your Level 9 Fireball to Level 12 without a full re-slot.
Uncut gem quick reference

How Do You Get Uncut Skill Gems?
Uncut Skill Gems are the ones you'll have the most of, because the campaign hands them out and they drop constantly:
- Quest rewards (guaranteed). The early Acts give you several Uncut Skill Gems for free — this is how you unlock your first abilities. These quest versions start at gem Level 1. Never sell or vendor early ones; you'll want the skill slots.
- Monster drops (the main source). Uncut Skill Gems have a base world drop level of 4 and then drop randomly from enemies everywhere after that. The rule that governs everything: the level of the gem that drops is tied to the monster/area level. Farm a Level 65 zone, you see mid-tier gems; farm an endgame map, you see high-tier gems.
- Currency Exchange / trade. If you need one specific high-level gem right now, buying it is almost always faster than farming (more on that below).
Because they scale with area level, the practical takeaway is simple: you don't farm Uncut Skill Gems in a special zone — you farm them wherever the monster level is highest for your progress point. During the campaign that's just "keep pushing forward"; in endgame it's "run the highest Waystone tier you can clear."
How Do You Farm Uncut Support Gems?
Support Gems are rarer than Skill Gems and you'll feel the pinch mid-campaign when you have skills but nothing to link them to. Sources:
- Monster drops, same area-level scaling as Skill Gems, but at a lower drop rate.
- Act chest and event rewards, especially the marked/gold chests and side areas in Act 3 (Utzaal) — a strong non-random way to bank Uncut Support Gems before you hit maps.
- Endgame mapping, where quantity/rarity modifiers and pack size multiply every gem drop.
Once you're mapping, Support Gems stop being scarce — the bottleneck shifts entirely to high-level gems (see the Level 20 section).

How Do You Get Uncut Spirit Gems?
Spirit Gems are the ones players ask about most, because you get so few and they gate your auras, heralds, and persistent buffs. Unlike Skill Gems, several Spirit Gem sources are guaranteed, which is why farming them is more about knowing the checkpoints than grinding:
- Guaranteed campaign drops. Specific bosses in Act 1 and Act 3 drop a guaranteed Uncut Spirit Gem, and the Golden Tomb marked chest in the Lost City (Act 2) contains one.
- Quest reward. In the Hunting Grounds questline, defeating The King in the Mists grants a Gembloom Skull; right-click it to receive an Uncut Spirit Gem.
- Monster drops. After the guaranteed sources, higher-level Uncut Spirit Gems drop randomly from enemies as you progress — again, scaling with area level.
If you're short on Spirit itself (not the gems), remember Spirit also comes from your weapon/gear implicits and certain uniques — the gems only decide which persistent skills you can run, not how much Spirit you have.
How Do You Get Level 20 Uncut Skill Gems?
This is the real endgame chase and the reason most players end up here. A Level 20 Uncut Skill Gem lets you engrave a max-level version of any skill (or level an existing one to 20), and they are brutally rare — one Reddit player reported their first Level 20 Uncut Skill Gem only after 330 hours of play. They don't have a dedicated farm; you stack the odds:
- Run the highest map tier. Level 20 gems require the highest monster levels in the game, which means Tier 15–Tier 16 Waystones (area level 80+). Nothing below that will drop them.
- Corrupt and irradiate the map. The consistent community finding (mobalytics, r/PathOfExile2) is that corrupted ground + irradiated maps push the effective monster level over the threshold. As one high-tier farmer put it, look for the Atlas node blue text that reads "+1 to Level of Monsters in Area," then run it as a T16, corrupted and irradiated.
- Maximize pack size and rarity. More monsters and more magic/rare packs = more gem rolls. Prioritize map and Atlas mods that add pack size, rare monsters, and quantity.
- Farm density mechanics. Any mechanic that floods the screen with monsters (Breach, Delirium, Expedition) multiplies your gem-drop attempts per map.
Level 20 gem farm setup at a glance
| Lever | Target | Why it matters |
|---|---|---|
| Waystone tier | T15–T16 (area level 80+) | Level 20 gems only drop at max monster level |
| Map corruption | Corrupted ground | Raises effective monster level |
| Irradiation | Irradiated map | Additional monster-level / difficulty push |
| Atlas node | "+1 to Level of Monsters in Area" | Stacks the level threshold |
| Map mods | +Pack size, +Rare monsters, +Quantity | More monsters = more gem rolls |
Even with a perfect setup, Level 20 gems are a low-single-digit-percent drop — treat them as a bonus while you farm currency, not a guaranteed payoff per map.
Should You Farm or Buy Uncut Gems?
Here's the honest math. Farming low and mid-level uncut gems is trivial — you'll drown in them during the campaign and early maps, so never buy those. But for a specific Level 19–20 Uncut Skill Gem, the time cost of grinding T16 corrupted maps for a low-percent drop is often worse than simply buying it.
You have two buy routes:
- Currency Exchange — the in-game shop lets you trade currency for gems directly, no player interaction needed.
- Player trade — list-and-buy the exact gem level you want.
For reference on the currency you'd spend, the softcore economy sat at roughly 1 Divine Orb ≈ 427 Exalted Orbs (≈ 7.5 Chaos Orbs) as of the latest 0.5.4 economy snapshot — Divine has been steadily deflating against Exalted all league, so always price-check live on poe.ninja or poe2scout before you buy. If you'd rather skip the grind entirely and jump straight to a maxed-out setup, that's exactly where a currency top-up or a boss/leveling carry pays for itself.

FAQ
What is an uncut gem in PoE2? An uncut gem is a raw gem you engrave into a finished gem. There are three types: Uncut Skill Gems (create active abilities), Uncut Support Gems (create support modifiers), and Uncut Spirit Gems (create persistent buffs, heralds, and auras). You right-click the uncut gem and pick which gem to create, at that gem's level or lower.
How do you farm uncut gems fast in PoE2? Farm the highest area/monster level you can clear — gem drop level scales with monster level, so pushing higher zones (and, in endgame, higher Waystone tiers) is the fastest way to see higher-level gems. Layer in pack-size, rarity, and density mechanics like Breach, Delirium, and Expedition to multiply your gem rolls per map.
How do you get a Level 20 Uncut Skill Gem? Run Tier 15–16 Waystones (area level 80+) that are corrupted and irradiated, ideally on an Atlas node with "+1 to Level of Monsters in Area," and stack pack size and rarity. They're a low-percent drop — one player reported their first only after 330 hours — so many players buy the exact gem on the Currency Exchange instead.
Can you level up existing gems with uncut gems? Yes. The in-game tooltip states an Uncut Skill Gem "Creates a Skill Gem or Level an existing gem to Level X." A higher-level Uncut Skill Gem can raise a skill you already use up to that gem's level, so save your high-level uncut gems for your main skills.
Where do you get Uncut Spirit Gems in PoE2? Guaranteed sources include specific Act 1 and Act 3 bosses, the Golden Tomb marked chest in the Lost City (Act 2), and the Gembloom Skull from defeating The King in the Mists. After those, higher-level Uncut Spirit Gems drop randomly from monsters as you progress.
Is it better to buy or farm uncut gems? Farm low and mid-level uncut gems — they're everywhere and never worth buying. For a specific Level 19–20 Uncut Skill Gem, buying on the Currency Exchange or via trade is usually faster and cheaper than grinding T16 corrupted maps for a rare drop.
