Uncut gem

Uncut Gems are a category of currency items and some quest items that can be used to engrave a skill gem or support gem, or level up a current skill gem.

At higher levels, uncut gems use an equity system such that players will find fewer lower level uncut gems as a percentage of lower level uncut gems will instead accumulate towards the drop of a higher level uncut gem. Between item levels 78-80, and even further between 81-82, this percentage increases significantly.

Uncut gem levels

Drop level breakpoints

The level of the gem dropped depends on the drop level. Note that Uncut Spirit GemUncut Spirit GemCreates a Persistent Buff Skill Gem or Level an existing gem to Level #Right Click to engrave a Persistent Buff Skill Gem.'s lowest level is 4 (drop level 12).

For example, if an Uncut Skill Gem drops from a normal monster in a level 40 area, it will always be a level 10 gem.

From drop level 62+, multiple tiers of uncut gems can drop based on a weighting system.

0.1.0	Introduced to the game.
