Quartz Locations

There are a lot of materials you’ll need to advance through Subnautica 2, and Quartz is one of them. It’s required to create the Glass resource, and between Glass and raw Quartz the following early-game tools, crafting stations, facilities can be created: the Flashlight, Scanner, Habitat Builder, Hatch, Fabricator, Vehicle Fabricator, Floor Lockers, Biobed, NOA Terminal, Scanner Station, Solar Panel and Dive Elevator, to name some prominent examples. Simply put, you’ll need a fair supply of Quartz to climb the tech tree in Subnautica 2, and this page will help you find it!

How to Find Quartz in Subnautica 2: To find Quartz in the early game, search for Coral Domes. Quartz can often be found growing on the pearlescent interior walls.

Page Breakdown

Quartz is required to create numerous essential items, like the Fabricator and the Scanner.

How to Find Quartz

In principle, Quartz shouldn’t be that hard to find - it’s an off-white mineral deposit found in the standard denominations, and unlike Copper it doesn’t even tend to blend into the brown-orange rock of the first biome. That said, it can appear somewhat scarce around the Lifepod if you’re wandering around scouring caves and the seafloor for random bits of Quartz, a search that’s made more complicated by the odd bit of Quartz you will inevitably find via this method.

Coral Domes

Instead of searching around blind for random deposits of Quartz, you instead want to look out for Coral Domes. These are large semi-circles of orangish coral that can be found on the seafloor. Swim under one of these domes and search the pearlescent interior and you’ll often find them lined with Quartz. These typically only house the smallest deposits of Quartz, but it makes up for a lack of per-unit Quartz with the sheer number of small deposits that can be found in most Coral Domes.

Alternatively you can find broken Coral Domes lying around - just look for shards of the pearlescent interior and if you spot one, give it a closer look to make sure there’s no Quartz on it.

You can find Quartz-bearing Coral Domes all around the Lifepod, including one Coral Dome just east of the Lifepod, with many more northeast of this first Coral Dome. As we said, if you’re searching the sea floor and caves for Quartz, you’ll probably end up with a scarce supply of the mineral, but once you know to search for Coral Domes, you’ll have all the Quartz you need and then some!

Once you’ve crafted the Sonic Resonator, you can add large deposits of Quartz to your list of viable collection spots.

Large Quartz Deposits

Later on in the game you’ll be able to craft the Sonic Resonator, which can be used to shatter large deposits of minerals, including Quartz. These are rarely found in Coral Domes and act more like normal minerals inasmuch as they’re found around the sea floor. The Coral Domes provide a sufficient amount of Quartz for all your early-game needs, but once you’ve climbed the tech tree a bit these large Quartz deposits will become a viable source of Quartz. You’ll find a few of them north of Camp One.

Now that you know exactly where to find the Quartz you need to get started, you can hopefully get off to a faster start than we did! Also remember that once you build the Scanner Station you can tag and track down individual deposits of Quartz within 300 meters of the Scanner Station.
