the diamond is a rare raw material in Subnautica Below Zero.
You can find it at depths of 200 meters or more, in several specific biomes. This guide covers the locations, mining methods, and uses of the ore.
What is a diamond in Subnautica Below Zero ?
the diamond is classified as a rare resource in the game. It is a bluish, translucent crystal that you can find on rock faces or on the seafloor.
It takes up only one slot in your inventory. You can gather it by hand from small outcrops, or at the Prawn using the drill boom on large deposits.
Diamonds are mainly used to craft advanced tools and vehicle upgrades. Always keep a few on hand: several end-game recipes require them.
What is a diamond used for in Subnautica Below Zero ?
Diamonds are an essential raw material for advanced recipes. Here are the ingredients for the main recipes that require them:
- Depth Module MkI for the SeaTruck ;
- Depth Module MkI for the Prawn ;
- Drill boom of the Prawn ;
- Laser blade (mining tool); ;
- Housing developer (renovation); ;
- Ionic cube.
The ionic cube, in particular, is tied to the game's main progression. Make sure you have at least four or five diamonds before tackling the deeper areas.
How to Get Diamonds in Subnautica Below Zero
There are two ways to mine this ore in Subnautica.
Small outcrops, hand-measured
On the seafloor and the rocky walls, look for the small, clear crystals that sparkle. You can break them with your bare hands in one snap.
These sites may also release copper, titanium, lead, or lithium. No special tools are required for this type of site.
Large deposits in the Prawn
Large rock deposits require the Prawn equipped with a drill arm. The Prawn It breaks open the deposit and releases several diamonds at once, often three or four crystals per deposit.
This is the most cost-effective way to quickly accumulate this ore. The Prawn It also withstands the pressure at great depths better, which limits the number of forced ascents you need to make to refill your oxygen.
To go 200 meters or more with the SeaTruck, start by adding a depth module. Without it, you'll quickly reach the shell limit before you get to the diamond-rich biomes.
Where to find diamonds in Subnautica Below Zero : the exact locations

Twisty Bridges (200–300 m)
This site is one of the first places where you can find diamonds in Subnautica Below Zero. The crystals grow on the walls of the rock arches at heights between 200 and 300 meters.
You can go ahead and use the SeaTruck and a depth module MkI.
Keep an eye on your O2: the tunnels can be disorienting during your first few dives. The biome's bioluminescent plants serve as visual landmarks in the narrow passages.
Purple Vents (150–300 m)
This site features outcrops right around the hydrothermal vents. The biome becomes accessible fairly early in the game.
In addition to ore, you'll find crystalline sulfur and salt deposits in the same areas. The bioluminescent trees and colorful plants make it easy to find your way around this biome.
Arctic Spires (300–500 m)
This biome contains deep ore deposits that are accessible only to Prawn. You'll find a variety of minerals at this site: copper, lithium, nickel ore, and silver ore are often found alongside diamond deposits.
Depth requires Prawn with a depth module to prevent hull damage. Spur-like rock formations characterize this biome and define the spawn zones for mineral deposits.
Deep Lilypads Cave (200–400 m)
This site is rich in resources of all kinds. Diamonds can be seen here on the rock faces, among the characteristic trees and plants.
It’s also one of the areas where you’ll find useful biological samples. The orin vine sample, the flat coral sample, and the gelatinous sac can all be collected from the same biome.
The Orin vine and its samples are used in several advanced recipes that you unlock midway through the game.
The vine sample and the coral sample round out the harvestable items in this area. Collect seeds and spores from the biome’s plants as you mine: some orin spores and seeds can be grown in your habitat.
Other Minerals and Associated Resources
In the same areas where diamonds are found, you'll often come across:
- Copper ore and raw copper on mixed outcrops; ;
- Silver ore and pure silver on the walls of the Arctic Spires ;
- Uraninite crystals in deep zones; ;
- Lithium and titanium are found in nearly all deep-sea biomes; ;
- Metal debris near the shipwrecks; ;
- Nickel ore at the deepest sites.
In Deep Lilypads Cave, also collects seeds and spores from plants in the biome.
The gelatinous sac and flat coral round out the harvestable items in this area. The gelatinous sac is useful for several advanced crafting recipes.
About the diamond in the first Subnautica
In the first game, diamonds work the same way. You can also find them in deep biomes, starting at 300 meters. Mining sites include volcanic areas and underwater caves such as the Bulb Zone or the volcanic islands.
If you play both games, note that the biomes and their names are completely different. This guide focuses on Subnautica Below Zero.
The method of extraction is the same for both: small outcrops mined by hand, large deposits at the Prawn with a drill arm.
Diamonds in Subnautica 1 is also a rare raw material. It is found in the same types of rock formations, at similar depths.
Console command to obtain a diamond
If you're playing in debug or creative mode, you can spawn a diamond directly using a console command. Open the console (key F3 then F8 to enable the debug console), then type:
item diamond
You'll receive a crystal directly in your inventory. This method only works if the console is enabled in the game options.
Summary of Sites by Depth
- Purple Vents : 150–300 m, outcrops around the chimneys; ;
- Twisty Bridges (bottom): 200–300 m, crystals on the arches; ;
- Deep Lilypads Cave : 200–400 m, rock faces and mixed terrain; ;
- Arctic Spires : 300–500 m, large deposits at the Prawn.
If you enjoy finding rare items in other video games, the article on the diamond layer in Minecraft follows a similar line of reasoning.
