In Starfield, the Caelumite mineral is commonly found near Artifacts. They are typically found within small caves rich in Caelumite deposits. As the game progresses, Caelumite becomes essential for advanced material and research.
While its value of 264 credits for 0.23 mass makes it profitable for selling. Typically, rare minerals in the game are needed for advanced research, including weapons, spacesuits, and outposts. This raises the question of whether Caelumite is used in the same way.
What is Caelumite Used For?
Caelumite is primarily used in advanced mods research projects and advanced armor mod crafting. Caelumite is needed to research level 3 spacesuits and helmet mods, and it is also needed to craft Gravitic Composites for spacesuits and helmets in slot 4. Additionally, Caelumite can also be used to craft Aid Items.
Reseach Projects
There are 3 levels in Helmet Mods and Spacesuit Mods, and only level 3 requires Caelumite for their research. Crafting and research are essential for creating weapon and armor modifications, spacesuit enhancements, medicines, food, and more. To craft an item, you need to finish a research project at the Research Lab to unlock its recipe.

Crafting Armor Mods
You can use Caelumite to craft armor mods, which allow you to upgrade your gear. These modifications can boost the fundamental physical, energy, and electromagnetic defenses of your armor. Additionally, they can offer increased protection against environmental hazards and grant unique enhancements to your skills and capabilities.
The types of Armor mods are Pack Mods, Boost Pack Mods, Spacesuit Mods, and Helmet Mods, and only Spacesuit Mods and Helmet Mods need Caelumite to craft.
