Lunar Core is the endgame crystal smelting product in Starsand Island, fired from Moonstone at the Furnace III. It sits at the top of the core family alongside Radiant Core and Starflare Core, and refines into Lunar Crystal at the Gear Smith.

Output | 1 Lunar Core |
Like every Furnace III recipe, Lunar Core runs on Oilstone as fuel, which is usually the bottleneck. Moonstone itself is mined in the mystical areas of the Moonlit Forest, where its blue glow marks deposits.
Lunar Crystal refinement. 3 Lunar Cores refine into 1 Lunar Crystal at the Gear Smith; the crystal feeds endgame robots and tools.
Clothing recipes. A dozen Sewing Table pieces, including boots, trousers, and dresses, consume Lunar Cores directly.
Mine Moonstone in bulk. Between clothing recipes and crystal refinement, each project tends to want 4 to 12 cores, which means 16 to 48 Moonstone per project.
Save Oilstone for what matters. Lunar Core competes with Eternal Alloy, Aurorite Ingot, and Flamecore Ingot for the same Oilstone supply.
