Where to find Noctilucous Jade in Genshin Impact (Interactive Map & Vendor)

Only 46 Noctilucous Jade rocks spawn in the overworld at any given time in Genshin Impact, making it one of the rarest Ascension Materials to find. However, collecting it is a different story, as each ore can drop up to three of them at a time. There is also one vendor that sells them every three days and one NPC that gives away four of them (but only once).

The highest concentration of Noctilucous Jade is in Mingyun Village. 25 out of 46 of this ore spawn here, making it the first location that Travelers should go to if they need this Ascension Material. There are several Teleport Waypoints here, not to mention a Statue of the Seven and a Domain for easy access.

Otherwise, Travelers will find this ore located throughout Liyue. It counts as a Liyue Local Specialty, meaning that Qiqi and Yanfei's Passives can hypothetically scout it out. Ningguang's Passive will sadly not scout it out on the minimap due to its Local Specialty status.

All Local Specialties respawn in 48 hours after they're harvested, including this ore (as it counts as a Liyue Local Specialty).

So far, only one vendor sells Noctilucous Jade in Genshin Impact, and that's Shitou. Travelers can find this merchant north of the crafting bench in Liyue Harbor, near the eastern Teleport Waypoint. All players have to do is talk
