Radiant Star gem


From Diablo Wiki

Jump to: navigation, search

Radiant Star gems are the 14th rank of gem in Diablo 3 and Reaper of Souls. These gems never drop and can only be created by upgrading Perfect Star gems via the Jeweler.

The Radiant Star gem is skipped over by players in Reaper of Souls, where Marquise and Imperial gems drop from lvl 61+ enemies.


With the closure of the Auction House and the advent of D3v2, players must find their own Flawless Squares to upgrade to higher level gems, rather than simply buying them in the Auction House. As each Perfect Star gem requires 729 Flawless Squares to upgrade, these gems are almost impossible to make in the post-AH era.
