If 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.

Once you have your Celestine, you can process it (at the Processor) into the Strontium you need for the depth module. While you're here, you might also want to know how to get Creature Enamel. Otherwise, here's where to find Celestine.

Subnautica 2 Celestine location

You can find Celestine in the biome around the Alien Ruins research base, but specifically, at lower depths. There's a great location about 200 meters southeast of the Alien Ruins, over the cliff, and down to the rocks below, though beware of the two Needlers patrolling nearby. There's loads of Celestine in and around the Needler nest here, but obviously, the closer you get, the more dangerous it is.

Assuming you don't have the Tadpole Depth module yet (otherwise why would you be searching for Celestine), you'll have to exit your Tadpole at 250 meters down and swim a short way to smash the Celestine nodes with your Sonic Resonator. Each node looks like a bunch of small, light blue, jagged crystals, a little similar to how big nodes of salt look.

If you're unsure, watch the video above for the exact location. Since Celestine is quite deep as materials go, this location is definitely your best bet while remaining relatively close to your Tadpole for oxygen and protection from Needler projectiles. Now, simply head back to your base, assuming you set one up nearby, and process that Celestine into Strontium.
