Minecraft resource gathering/Amethyst

Amethyst blocks are a decorative block found in Geodes. Its texture is purple with sparkles, and it makes unique sounds when walked on, broken, placed or hit.

Versions
Amethist blocks were added in the the Caves and Cliffs Part 1 update (1.17), and first appeared in snapshot 20w45a.

Acquiring
Amethyst blocks generate inside amethyst geodes, which can be found underground at lower altitudes. Amethyst geodes have an outer layer of smooth basalt, a middle layer of calcite and an inner layer of amethyst.

Amethyst blocks are of two types, regular and budding. Budding amethyst has an X on it and grows amethyst crystals over time. Do not attempt to destroy it as it does not drop anything.

Amethyst crystals can be farmed using a piston and observer. Nine amethyst crystals in a 3x3 grid can be crafted into an amethyst block.
