Its main known use is in tailoring: placing Lunarite in the spool of the 
Because Lunarite comes from both Frozen Geodes and Omni Geodes, it can appear alongside a wide range of other geode loot. Omni Geodes in particular are useful when hunting for a specific mineral since they can produce many different items, while Frozen Geodes provide an additional source through standard geode opening. Players who are trying to complete their museum collection or build up tailoring materials may therefore want to process geodes instead of selling them unopened.
In practical terms, Lunarite is one of those minerals that is worth saving until the player knows whether they need it for tailoring. If the Goodnight Shirt is desired, Lunarite should be kept for the Sewing Machine; otherwise, it can be treated as part of the broader pool of geode finds. Since the game’s geode rewards are varied, obtaining Lunarite is often a matter of patience and repeated geode processing rather than a guaranteed route.
