The Sunset-Blue Obsidian Ring in Genshin Impact is a Key Item crafted by combining three Sunset-Blue Obsidian Fragments. See the location of the Sunset-Blue Obsidian Fragments, how to open the Collective of Plenty Secret Trove, and all the info about it here in this guide!

Sunset-Blue Obsidian Ring Location

Within the Borders of Collective of Plenty

Sunset-Blue Obsidian Fragments can only be obtained from chests or Warrior Challenges that are originally found within the vicinity of the Collective of Plenty territory.

Natlan Interactive Map and Location

Found in Precious or Luxurious Chests

Fragments of the Sunset-Blue Obsidian Ring can be found by opening Precious or Luxurious Chests in Natlan. You will initially get Sunset-Blue Obsidian Fragments and three pieces automatically form one Sunset-Blue Obsidian Ring.

To make the search more challenging, you can only get Obsidian Fragments by chance, which means not all Precious or Luxurious chests you open guarantee a piece of Obsidian Fragment inside.

Reward From Warrior's Challenges

Sunset-Blue Obsidian Fragments can also be obtained from Warrior Challenges within the area of the Collective of Plenty tribe. Completing a Warrior Challenge can grant you a Sunset-Blue Obsidian Fragment from the Precious Chest it rewards.

This is not guaranteed however and is still by chance.
