An amethyst geode.
Amethyst geodes are underground structures which serve as the only source of amethyst, tuff, and calcite.
Generation
Amethyst geodes generate underground anywhere between sea level and bedrock. It overrides cave and ravine generation but not abandoned mineshafts as well as other structures.
Structure
Amethyst geodes consist of a hollow shell of blocks of amethyst with budding amethyst blocks randomly generated throughout. Amethyst crystals generate within the structure on any amethyst block. Surrounding the amethyst is a shell of calcite, which itself is surrounded by a shell of tuff.
