Subnautica 2 Celestine: How to Farm This Resource
In brief
Celestine is an essential resource in Subnautica 2 used to build high-tech equipment and upgrade your vehicles. Found in the alien biome about 1200 meters east of your pod, this silvery-blue resource is efficiently harvested with a Sonic Resonator from a strategically placed base.
In Subnautica 2, Celestine allows you to build high-tech equipment and upgrades for your submarines. This article will detail the steps to follow to find and exploit it properly.
What is Celestine?
Celestine is an essential crafting material found in the alien biome located east of the hot zone. This ore can be recognized by its silvery-blue color as well as its small crystalline protrusions.
Celestine is mainly used to build the following elements:
- Modification stations
- Vehicle upgrades
- Strontium

Locating Celestine
Celestine is therefore located in the alien biome, about 1200 meters east of your survival pod. In this place, you will come across alien structures of course, and very dark blue water. To find Celestine, head towards the south of the Alien Ruins at a depth of 250m. You will find Celestine attached to the rocky walls.
Tip
Consider using a vehicle to make your exploration easier.
Here is the minimum equipment to bring:
- Sturdy vehicle: The Seatruck is recommended for traveling more safely.
- Building tools: Your Habitat Builder and the materials needed for the planned installations.
- Scanner station: it will allow you to locate Celestine more easily.
Note
Make sure you have sufficient oxygen reserves.

Harvesting strategies
Building a base in the alien biome should help a lot with Celestine harvesting. With a base containing a Scanner station, you will be able to monitor nearby resources. Even more so if the base is close to a current that will power your hydraulic turbines.
Use the Sonic Resonator to extract Celestine. This device will allow you to fill your vehicle's storage as needed without damaging it. Look for the silver-blue ore nodes and activate the Resonator to easily collect the ore.
