Calcite – Minecraft Wiki

Calcite is a carbonate mineral, currently used as a decorative block. Calcite drops as an item if mined by any pickaxe. If mined without a pickaxe, it drops nothing. Calcite generates naturally as part of the structure of amethyst geodes, between the smooth basalt and block of amethyst layers. It also generates in the stony peaks in strips. Calcite is currently …
