Legendary Gems are gems in Diablo III that are only socketable in amulets and rings. They only drop from Rift Guardians in Greater Rifts. In addition to the gems being unique equipped, any one character can not even receive any gem that they already have in their possession, including the shared stash. The gems are dropped at Rank 0 and can be upgraded by speaking with Urshi.[1] Legendary gems do not work when equipped on a follower.[2]

These gems can be upgraded by speaking with Urshi, who will appear on every level of a Greater Rift after the Rift Guardian has been defeated on that level. It does not cost anything to upgrade the gem. The blue property on the gem is the only property that will be upgraded. The upgrade success rate, and chance to gain multiple ranks with a single upgrade will increase as the Greater Rift level increases, but it also decreases with the rank of the gem, i.e. one will need higher Tier to even have a chance to upgrade the high-level gems. The maximum number of attempts Urshi can offer per run is three. When the gem reaches rank 25, it will gain a secondary power, which is not empowered by further rank increases.[4]
