Calcite generates as the inner shell of amethyst geodes — the bright cream-white layer that sits between the smooth basalt outer hull and the budding amethyst at the geode's core. Mining a single geode yields several hundred blocks of this material, making it one of the most accessible naturally-occurring near-white surfaces in the game. Outside of geodes, the block does not generate at all; it is exclusively a geode product.

The texture is a soft cream tone with delicate crystalline veining, brighter and warmer than diorite, smoother than quartz, and noticeably less reflective than bone block. For builders, this opens up a clean light primary palette without resorting to dyed materials: pair calcite with smooth basalt for cool grey-on-cream contrast, with copper variants for bronze-on-pale palettes, or with dark deepslate for high-contrast modern interiors. Calcite has no variant family — no slabs, stairs, or walls — and exists only as a full block. Mining requires a stone-tier or higher pickaxe to register any drop.
