Normally, collecting Precious and Luxurious chests only rewards 
Primogems and other valuable items, such as Artifacts in Genshin Impact. In version 5.0, Natlan was released and introduced three tribes, including the Children of Echoes.
When you open Precious or Luxurious chests in the Children of Echoes' area (Tequemecan Valley), there is a chance of obtaining a Yellow Obsidian Fragment. Once players collect all three pieces, they can craft them into a Yellow Obsidian Ring in Genshin Impact, which can unlock the Obsidian Barrier in the Children of Echoes' tribe area.

Yellow Obsidian Ring & Fragments Locations In Genshin Impact
The Yellow Obsidian Ring in Genshin Impact can be crafted from the inventory using three Yellow Obsidian Fragments. To get the Fragments, players must open Precious and Luxurious chests in the Children of Echoes area (Tequemecan Valley). The drop is random, so Travelers may have to open all the chests before they get what they need.
There are a lot of chests scattered around the Children of Echoes area that can reward you with three pieces of the Yellow Obsidian Fragments. Some of these chests are locked behind quests or puzzles in Genshin Impact.
