Ruby
Ruby is a precious red gemstone found in deep biomes. Used in advanced electronics and aerogel crafting, it serves as a key ingredient in mid-to-late game progression, bridging the gap between basic electronics and endgame-tier components.
Quick Info
How to Get & Where to Find
Mine Ruby from seabed outcrops in deep biomes. Look for red glowing deposits on the seafloor and in cave systems. Ruby shares outcrop spawns with other deep resources, so expect to break several before a Ruby drops. A Seamoth with depth protection or a Prawn Suit is recommended for the 200–800m range.
Deep Waters
200–500m — red glowing outcrops on the seabed. Most accessible Ruby source for mid-game.
Mid-game — best entry pointLava Zone
600–800m — dense Ruby deposits in the molten depths. Higher yield but extreme danger.
Endgame — extreme heatLost River
300–600m — occasional Ruby outcrops along the green riverbed corridors.
Mid-late game alternativeUses & Recipes
Ruby is a versatile advanced material. Aerogel is a core ingredient in high-tier thermal protection, while the advanced Computer Chip unlocks sophisticated fabrication recipes. The Scanner Room HUD Chip dramatically improves your ability to locate resources on the map.
Aerogel
Lightweight insulating material used in thermal suits and advanced equipment.
Computer Chip (Advanced)
Upgraded processing unit for complex fabrication recipes and base modules.
Scanner Room HUD Chip
Projects resource scan results directly onto your HUD for targeted harvesting.

Tips & Strategy
Look for Red Glow
Ruby deposits emit a faint red glow on the seabed, making them easier to spot in dark deep biomes. Use your flashlight sparingly and let the ambient glow guide you to outcrops.
Scan with the Scanner Room
Build a Scanner Room near your deep biome base and set it to scan for Ruby. The HUD chip upgrade projects resource pings directly onto your visor, eliminating guesswork during farm runs.
Pair with Gel Sack Runs
Aerogel requires both Ruby and a Gel Sack, and both spawn in overlapping deep biomes. Plan a combined farm route to collect both ingredients in a single dive and craft Aerogel immediately on return.
Craft Aerogel First
Aerogel unlocks thermal protection gear that is essential for reaching the Lava Zone. Prioritize Aerogel over the advanced Computer Chip so you can safely access the deeper biomes where rarer resources spawn.
Map Locations
Ruby outcrops cluster in Deep Waters and the Lava Zone, with occasional spawns in the Lost River. Pin Ruby farming routes on the interactive map to plan efficient mid-to-late game dives with Scanner Room coverage.

Frequently Asked Questions
Where to find Ruby?
Ruby is found in Deep Waters (200–500m) and the Lava Zone (600–800m), with occasional spawns in the Lost River. Look for red glowing deposits on the seabed and mine them from outcrops. The deep waters are the most accessible source for mid-game players.
What is Ruby used for?
Ruby is used for Aerogel (a key thermal protection ingredient), the advanced Computer Chip (for complex fabrication), and the Scanner Room HUD Chip (which projects resource pings onto your visor). It is a core ingredient in mid-to-late game electronics crafting.
Is Ruby rare?
Ruby is considered uncommon. It is not as rare as Kyanite or Diamond, but it is less common than basic ores like Copper or Titanium. Ruby shares outcrop spawns with other deep resources, so you may need to break several outcrops before a Ruby drops.
