Red Gems are a resource introduced in Aberration and also available on Valguero, Genesis: Part 1, Crystal Isles, Genesis: Part 2, Lost Island, and Fjordur. They are used for crafting various items.


Red Gems can be mined from the various red or purple crystalline formations found in The Spine. They can also rarely be found from Roll Rat diggings and Earthquake Debris, however a Roll Rat will become aggressive if you pick their debris.


Red Gems are used to craft the following items:

Aberration Farming Strategy

Early game : First you'll need a small amount of Red Gem to craft a  Gas Collector, which will allow you to craft the  Hazard Suit Armor you need to get more Red Gem in the radioactive zone. To gather a small amount of Red Gem, simply follow a  Roll Rat until it drops Red Gems (rarest drop). Picking up Gems dropped by a Roll Rat will aggro it, so be prepared to either kill it or run away from it.

You can also use the  Lamprey's  Lamprey Charge status effect or, if you have access to Genesis: Part 2, use the provided  Federation Exo Armor, and risk the late game option described below, but beware of the dangerous creatures in these sections of the map.

Late game : The  Aberrant Ankylosaurus is not recommended, it is not immune to radiations and it lacks the speed, stealth and mobility to reach the deepest parts of the radioactive zone where the best red crystal veins lie. The best strategy is to harvest Red Gems with a  Metal Pick. To maximize your yield, you need to craft a Metal Pick from a high quality blueprint, which you can find in the Surface beacons. If you find a high quality blueprint:

Now that you are ready to harvest Red Gems with high efficiency, equip a Hazard Suit Armor or a full  Tek Armor set, take your best charge pet and your best  Rock Drake (for which you might want to invest in  Weight) and head to the entrance of the radioactive cave. Outside the cave, there are plenty of red and purple crystal nodes. There are at least 4 huge veins of Red Crystals from which you can gather over 20,000 Red Gems in less than an hour (official rates). And there are at least 5 more huge veins a bit further from which you can harvest as many Red Gems. Use your Rock Drake to clear the area of hostiles. If you come across a Reaper Queen, lure it down some cliff as it may overpower your drake. Put your drake on follow to unload your Red Gems regularly (every 5 or 6 hits) and use a Vault to unload your Drake.


  • For some reason, currently purple crystals (similar in shape to the spiky green gem crystals) supply Red Gems, but only in Element Chambers.
  • While Red Gems can be gathered by tools, the amount is not high and the danger is great. It is advised to use an  Ankylosaurus held by a carrying  Karkinos.
  • On Extinction,  Red Crystalized Sap can be used as a substitute.
  • On Valguero, Red Gems are found in The Unknown (radiation zone).
  • On Crystal Isles, Red Gems are found in Eldritch Isles as well as green and blue gems from harvesting the smaller blue crystals found there.
  • On Fjordur, Red Gems are found in bottom of The Throat of Flames near the Magmasaur nests, as well as smaller amounts in the easier Beiygjaheimr cave.
