Here’s the latest on Celestine in Subnautica 2 based on recent gaming coverage.
- What Celestine is used for: Celestine is a rare resource used to upgrade equipment, notably components tied to deeper exploration (e.g., depth modules for submersibles). It’s described as material you craft with to enhance depth capabilities, allowing safer dives at greater depths.[1][2]
- Where to find it: The current guidance points to the Alien Ruins biome area as the primary Celestine source, typically at deeper depths near the alien structures and around Needler nests. A common location cited is roughly 200 meters southeast of the Alien Ruins, down to rocks and cliffs where Celestine nodes are found, though it’s near hostile fauna. The Tadpole submersible is often recommended to access these deeper zones, and players may need to disembark at around 250 meters to harvest Celestine with a Sonic Resonator.[2][3][1]
- How to harvest: Celestine appears as light blue, jagged crystal nodes. Players typically use tools like the Sonic Resonator to mine or harvest these nodes in the Celestine-rich areas within the Alien Ruins vicinity. After collecting Celestine, it’s used at the Modification Station to craft or upgrade depth-related equipment for the Tadpole or other modules.[1][2]
- Community notes and guidance: Several community threads and guides highlight that Celestine locations can be deep and near aggressive creatures (e.g., Needlers), so players often advise approaching with the Tadpole and planning for oxygen and safety while mining. You’ll find additional how-to content and location tips across video guides and PC gaming outlets, which consistently reference the Alien Ruins region as the main Celestine source.[4][5][6]
Illustration: Deep-water Celestine node cluster around the Alien Ruins, accessed best with the Tadpole, located near blue crystal-like deposits and guarded by Needlers.
If you want, I can pull more specifics on exact coordinates, alternative Celestine spots from different patches, or summarize step-by-step farming routes with map-relative directions. I can also compare Celestine to similar deep-sea resources in Subnautica 2 to help plan a broader expedition.

The game is sending me to depths way beyond my capabilities. I need clestine to progress but cant find the damn thing I been going around in circles trying to find it but no luck. Does anybody know where to find that stupid celestine?

wikily.ggIf you're in need of Celestine in Subnautica 2, that means you're finally ready to craft that Tadpole Depth module—say goodbye to imminent hull breaches everytime you try to dive. You can only get Celestine in the biome around the Alien Ruins, meaning you have to complete the Tadpole Pens and cross that vast and spooky stretch of sea to this new biome... [
