Quartz is one of the most important resources you will find during the early hours of Subnautica 2. At first it might seem like just another crafting material scattered around the ocean floor, but before long you will realize just how many essential blueprints depend on it.
You need Quartz to craft Glass, and Glass is used in a huge number of important tools, machines, and base components. Even early survival equipment like the Scanner and Flashlight rely on it, alongside bigger upgrades such as the Habitat Builder, Vehicle Fabricator, Scanner Station, Solar Panels, and Dive Elevators.
In other words, if you want to progress smoothly through the early game, you are going to need a lot of Quartz.
The tricky part is that many new players spend far too much time randomly searching caves and the seafloor for tiny deposits. While you can find Quartz this way, it is honestly one of the slowest and most frustrating methods possible.
Thankfully, there is a much easier way to farm it once you know what to look for.
Subnautica 2 Quartz Locations Guide
If you want reliable Quartz early on, focus your search around Coral Domes.
These are large orange coral formations shaped almost like giant underwater half-spheres resting on the ocean floor. They are very easy to miss at first because they blend naturally into the environment, but once you recognize them, finding Quartz becomes dramatically easier.
The real secret is not the outside of the Coral Dome, but the inside.
When you swim underneath a Coral Dome, you will notice the interior has a shiny pearlescent texture. Quartz deposits commonly grow directly along these inner walls, often in large numbers packed close together.
Instead of finding one random Quartz piece every few minutes while wandering the ocean floor, a single Coral Dome can contain enough Quartz to completely fill your inventory early on.
Where to Find Coral Domes Near the Lifepod
The good news is that you do not need to travel very far to start farming Quartz efficiently.
One of the easiest Coral Domes to find is directly east of the Lifepod. Once you locate that first dome, you can continue exploring northeast to find several more nearby.
This area is honestly one of the best beginner resource zones in the game because you can gather large amounts of Quartz without dealing with especially dangerous creatures or deep underwater exploration.
If you are just starting out and need materials for your first base pieces or tools, this should absolutely become one of your regular farming routes.
Quartz on the Ocean Floor
You can still occasionally find Quartz deposits lying openly across the seafloor or tucked inside caves.
These deposits are easy to recognize because Quartz has a pale off-white appearance that stands out more clearly than some other resources like Copper or Titanium. Unlike Copper, which often blends into the surrounding rocks, Quartz is usually easier to spot once you know its shape and color.
The problem is consistency.
Searching randomly across the seabed usually results in very small amounts of Quartz over long periods of time. You might pick up one piece here and another piece there, but it is nowhere near as efficient as farming Coral Domes directly.
For that reason, random seabed searching works best as supplemental gathering rather than your main farming method.
Broken Coral Domes Also Contain Quartz
Another useful trick many players overlook is checking broken Coral Dome fragments.
Sometimes you will find shattered pieces of Coral Dome scattered across the seafloor. These broken sections still expose the same pearlescent inner material found inside intact domes, and Quartz can grow directly on these fragments as well.
If you spot shiny white or reflective coral shards lying on the ocean floor, it is usually worth taking a closer look.
Even small fragments can sometimes contain multiple Quartz deposits.
Why Quartz Is So Important Early On
The reason Quartz becomes such a high-priority resource is because it connects to so many important upgrades and progression systems.
Some of the most useful early-game items requiring Quartz include:
- Scanner
- Flashlight
- Habitat Builder
- Fabricator
- Solar Panel
- Hatch
- Vehicle Fabricator
- Scanner Station
- Floor Lockers
- Biobed
Many of these are not optional tools either. They form the foundation of your survival progression.
Without enough Quartz, players often end up delaying important upgrades simply because they cannot craft enough Glass or complete key building recipes.
That is why learning proper Quartz farming routes early saves a huge amount of time later.
Large Quartz Deposits
As you progress deeper into Subnautica 2, you will eventually unlock the Sonic Resonator.
This tool changes resource gathering significantly because it allows you to break apart large mineral deposits, including massive Quartz formations.
Unlike the smaller Quartz nodes found in Coral Domes, these larger deposits are usually found directly on the seabed in deeper areas.
They are not especially common early on, but once your technology improves they become one of the best long-term ways to gather large quantities of Quartz quickly.
You can find several large Quartz deposits north of Camp One later in the game.
At that stage, resource gathering becomes far more efficient than the slower early-game collection methods.
Scanner Station Tip
Once you finally build a Scanner Station, Quartz farming becomes much easier.
The Scanner Station allows you to track nearby Quartz deposits within a large radius around your base. Instead of manually searching every Coral Dome yourself, you can simply tag Quartz and follow the markers directly to the resource nodes.
This becomes incredibly useful later once your crafting needs start increasing and you need steady supplies for advanced base construction.
Quartz might seem like a simple beginner material, but it is honestly one of the most important resources in all of Subnautica 2’s early progression.
The biggest mistake new players make is searching blindly across the ocean floor instead of targeting Coral Domes directly. Once you understand that Coral Domes are effectively natural Quartz farms, gathering the resource becomes dramatically easier.
If you are struggling to keep up with crafting demands early in the game, make a habit of checking Coral Domes regularly. Between the domes east of the Lifepod and the nearby northeastern clusters, you should have more than enough Quartz to support your early survival journey.
